Your Keeper account and stored data will reside in the EU (Dublin) data center.
Keeper utilises best-in-class security to safeguard your information and mitigate the risk of a data breach.
ONLY the user has knowledge of and access to their Master Password and key that is used to encrypt and decrypt their information.
User data is encrypted and decrypted at the device level not on Keepers servers or in the cloud.
Keeper protects your information with AES 256-bit encryption and PBKDF2, widely accepted as the strongest encryption available.
Keeper utilises Amazon AWS in multiple geographic locations to host and operate the Keeper Vault and architecture providing customers with the fastest and safest cloud storage. Data at rest and in transit is fully isolated in a customer's preferred global data center.
Keeper supports multi-factor authentication, biometric login and Keeper DNA which uses personal devices like your smartwatch to confirm your identity.
KSI is a Zero-Knowledge security provider. The Keeper user is the only person that has full control over the encryption and decryption of their data. With Keeper, encryption and decryption occurs only on the user's device upon logging into the vault. Each individual record stored in the user's vault is encrypted with a 256-bit AES key that is randomly generated on the device. The record keys are protected by an additional key, called the Data Key. The Data Key is encrypted by a key derived on the device from the user's Master Password. Data stored at rest on the user's device is also encrypted by another key, called the Client Key. Secure record syncing between the user's devices is also encrypted at the network layer and routed through Keeper's Cloud Security Vault. This multi-tiered encryption model provides the most advanced data protection available in the industry.The encryption key that is needed to decrypt the data always resides with the Keeper user. KSI cannot decrypt the user's stored data. KSI does not have access to a customers' master password nor does KSI have access to the records stored within the Keeper vault. KSI cannot remotely access a customers' device nor can it decrypt the customers' vault. The only information that Keeper Security has access to is a user's email address, device type and subscription plan details (e.g. Keeper Unlimited). If a user's device is lost or stolen, KSI can assist in accessing encrypted backup files to restore the user's vault once the device is replaced.Information that is stored and accessed in Keeper is only accessible by the customer because it is instantly encrypted and decrypted on-the-fly on the device that is being used - even when using the Keeper Web App. The method of encryption that Keeper uses is a well-known, trusted algorithm called AES (Advanced Encryption Standard) with a 256-bit key length. Per the Committee on National Security Systems publication CNSSP-15, AES with 256-bit key-length is sufficiently secure to encrypt classified data up to TOP SECRET classification for the U.S. Government. The cipher keys used to encrypt and decrypt customer records are not stored or transmitted to Keeper's Cloud Security Vault. However, to provide syncing abilities between multiple devices, an encrypted version of this cipher key is stored in the Cloud Security Vault and provided to the devices on a user's account upon successful vault login and multi-factor authentication. This encrypted cipher key can only be decrypted on the device for subsequent use as a data cipher key.
It is highly recommended that customers choose a strong Master Password for their Keeper account. This Master Password should not be used anywhere outside of Keeper. Users should never share their Master Password with anyone.
To protect against unauthorized access to a customers' account, Keeper also offers Two-Factor Authentication. Two-Factor authentication is an approach to authentication requiring two or more of the three authentication factors: a knowledge factor, a possession factor, and an inherence factor. For more information on Two-Factor Authentication see this link.Keeper uses something you know (your password) and something you have (the phone in your possession) to provide users extra security in the case where your master password or device is compromised. To do this, we generate TOTPs (Time-based One-Time Passwords).Keeper generates a 10-byte secret key using a cryptographically secure random number generator. This code is valid for about a minute, and is sent to the user by SMS, Duo Security, RSA SecurID, TOTP application, Google Authenticator or Keeper DNA-compatible wearable devices.When using the Google Authenticator or TOTP application on your mobile device, the Keeper server internally generates a QR code containing your secret key, and it is never communicated to a third party. Each time a user deactivates, then reactivates Two-Factor Authentication, a new secret key is generated.To activate Two-Factor Authentication, visit the Keeper DNA or Settings screen of the Keeper Web App. Keeper Business customers can optionally enforce the use of Two-Factor Authentication and supported 2FA methods via the Keeper Admin Console's role enforcement functionality.
Keeper supports FIDO-compatible U2F hardware-based security key devices such as YubiKey as a second factor. Security keys provide a convenient and secure way to perform two-factor authentication without requiring the user to manually enter 6-digit codes. Multiple security keys can be configured for a user's vault. For platforms that do not support security key devices, users may fall back to other configured 2FA methods. To configure a security key and other two-factor authentication methods, visit the 'Settings' screen of the Keeper application.
Keeper supports the ability to add up to 5 emergency contacts to grant vault access in the event of an emergency or death. Once a specified wait time has elapsed, the emergency contact will gain access to the user's vault. The process of sharing a vault is Zero-Knowledge, and the user's Master Password is never directly shared. RSA encryption is utilised to share a 256-bit AES key with the emergency contact, at the expiration of the wait time set by the originating user. Therefore, the emergency contact must have a Keeper account (and a public/private RSA key pair) to accept the invitation.
During account signup, users are asked to select a Security Question and Answer. Also during signup, Keeper generates a Data Key which is used to encrypt and decrypt the Record Keys stored with each of the vault records. The user's Data Key is encrypted with the Master Password, and each Record Key is encrypted with the Data Key. Each record in the user's vault has individual, different Record Keys.The way account recovery works is by storing a second copy of the user's data key that is encrypted with the selected Security Question and Answer. To complete a vault recovery, the user is required to enter an email verification code, and also the Two-Factor Authentication code (if enabled on the account). We recommend creating a strong security question and answer, as well as turning on Keeper's Two-Factor Authentication feature from the 'Settings' screen. Two Factor Authentication can also be enforced for Keeper Business customers via the Keeper Admin Console.
Data is encrypted and decrypted on the user's device, not on the Cloud Security Vault. We call this "Client Encryption" because the client (e.g. iPhone, Android Device, Desktop App, etc.) is doing all of the encryption work. The Cloud Security Vault stores a raw binary which is essentially useless to an intruder. Even if the data is captured when it's transmitted between the client device and Cloud Security Vault, it cannot be decrypted or utilised to attack or compromise the user's private data.Breaking or hacking a symmetric 256-bit key would require 2128 times the computing power of a 128-bit key. In theory, this would take a device that would require 3×1051 years to exhaust the 256-bit key space.
Each user has a 2048-bit RSA key pair that is used for sharing records and messages between users. Shared information is encrypted with the recipient's public key. The recipient decrypts the shared information with their private key. This allows a user to share records only with the intended recipient, since only the recipient is able to decrypt it.
Keeper uses PBKDF2 with HMAC-SHA256 to convert the user's Master Password to a 256-bit encryption key with up to 100,000 rounds. PBKDF2 iterations are based on the device platform and managed by the user in Keeper's 'Advanced Settings' screen.
All secret keys that must be stored (such as each user's RSA private key and the Data Key), are all encrypted prior to storage or transmission. The user's Master Password is required to decrypt any keys. Since Keeper's Cloud Security Vault does NOT have access to the user's Master Password, we cannot decrypt any of your keys or data.
The Cloud Security Vault refers to KSI's proprietary software and network architecture that is physically hosted within Amazon Web Services (AWS) infrastructure.When the user synchronizes their Keeper records with other devices on their account, the encrypted binary data is sent over an encrypted SSL tunnel and stored in Keeper's Cloud Security Vault in encrypted format.
Keeper maintains full encrypted version history of every record stored in the user's vault, providing confidence that no critical data is ever lost. From the Keeper client application, users can examine the record history and perform a restore of any individual vault record. If a stored password or file in Keeper is changed or deleted, users always have the ability to perform a point-in-time restore.
Customers who purchase Keeper Business are provided an extra layer of control over their users and devices. Keeper administrators are provided access to a cloud-based administrative console which allows full control over user on-boarding, off-boarding, role-based permissions, delegated administration, teams, Active Directory/LDAP integration, Two-Factor Authentication, Single Sign-On and security enforcement policies. Keeper's role-based enforcement policies are fully customizable and scalable to any sized organisation.
Keeper for Business provides a secure and robust set of controls over organisational units, roles, teams and shared folders. The powerful back-end controls of Keeper provide the most robust security layers that provide least-privilege access and full delegated administration.At the encryption layer, every record (e.g. password or credential) stored in the Keeper platform has a unique record identifier (Record UID). Each record is encrypted with a record key. Shared folders have a shared folder key, each team has a team key and a public/private key pair, and every user has a user data key, client key, and public/private key pair. Every role that requires the transferability of the user's account has a role enforcement key and a public/private key pair. Data at rest on the user's device is encrypted with the user's client key. The user's data key and client key are encrypted with the user's Master Password.Records created by a user have the record key encrypted with the user's data key. Records are added to a shared folder by encrypting the record key with the shared folder key. Records are directly shared to a user by encrypting the record key with the user's public key. Users are added to a shared folder by encrypting the shared folder key with the user's public key. Teams are added to a shared folder by encrypting the shared folder key with the team's public key. Users are added to a team by encrypting the team key with the user's public key.For Roles that enforce the transferability of a user's account:The enforcement key is encrypted with each admins' public key that is allowed to perform the transfer.(Note: separate enforcements applied to separate groups of users may be designated to be transferred by separate groups of admins.)The user's data key (for users in a role to which the enforcement is applied) is encrypted with the role enforcement's public key. An account to be transferred is done by locking then transferring and deleting a user's account. This ensures the operation is not performed secretly. The user's shared data key and metadata allow for the eventual ability to decrypt the record data, but do not allow direct access. Thus, only after the records have been assigned to an individual are the records now usable by that individual, and no other individual has gained access.All encryption is performed client side, and at no time does Keeper have the ability to decrypt the information being shared or transferred. Additionally, at no time is a user's client key shared. A user who is removed from a team, shared folder, or direct share will not receive new data from the team, shared folder, or record. Thus, although the key is compromised with that individual, the key is not usable for gaining access to the underlying data.Several different administrative privileges may be assigned to portions of a hierarchical tree that allows the members of the privileged role to perform operations in our Keeper Admin Console.Server-side and client-side enforcement policies may also be applied to roles to dictate the behavior of the client for groups of individuals.Teams enables easy distribution of shared folders to groups of users.
The Keeper Bridge integrates with Active Directory and LDAP servers for provisioning and onboarding of users. Keeper Bridge communication is first authorised by an admin with the privilege to manage the bridge. A transmission key is generated and shared with Keeper for all subsequent communication. The use of the transmission key is the authorization for all operations performed by the bridge except for the initialization of the Bridge. The transmission key may be regenerated at any time, and it will automatically rotate every 30 days.The transmission key is only for transmission which means a compromised key may be reinitialised or revoked without any loss of data or permission.Keeper Bridge may not give privileges to a role or user. It may add a user to a privileged role, as long as no enforcement keys are needed. Keeper Bridge may not elevate itself or a user above the portion of the tree it is managing. Not all operations are available to the Bridge, i.e. the Bridge can disable an active user, but may not delete the user. The admin will have to choose if the user is to be deleted or transferred.
Keeper can be configured by Keeper Business customers to authenticate a user into their Keeper vault using standard SAML 2.0 identity products. Keeper is a pre-configured service provider in every major SSO Identity Provider such as Google Apps, Microsoft Azure, Okta, Ping Identity and others. The mechanism that Keeper utilises to authenticate users into their vault in a Zero-knowledge environment is the patent-pending implementation called Keeper SSO Connect™. Keeper SSO Connect is a software application that Keeper Business administrators install on their own infrastructure (either on-premise or cloud), which serves as a SAML 2.0 service provider endpoint. When activated on a particular organisational unit, Keeper SSO Connect manages all of the encryption keys for Keeper Business end-users. Upon successful authentication in to the business Single Sign-On Identity Provider, the user is logged into Keeper with the necessary encryption keys to decrypt their vault. Keeper SSO Connect software operates on Windows, Mac and Linux environments.
In order to maintain Zero Knowledge security and ensure a seamless SSO experience for users, Keeper SSO Connect must be installed on the customer's server. Windows, Mac and Linux environments are fully supported with High Availability (HA) load balancing operational modes.Keeper SSO Connect automatically generates and maintains the Master Password for each provisioned user, which is a randomly generated 256-bit key. This Master Password is encrypted with the SSO Key. The SSO Key is encrypted with the Tree Key. The SSO Key is retrieved from the server upon Keeper SSO Connect service startup, and then decrypted using the Tree Key, which is stored locally on the server to support automatic service startup. Communication between SSO Connect and Keeper's Cloud Security Vault is protected with a Transmission Key.
KSI utilises Amazon AWS in North America and Europe, for localized data privacy and geographic segregation to host and operate the Keeper solution and architecture. Utilizing Amazon AWS allows Keeper to seamlessly scale resources on-demand and provide customers with the fastest and safest cloud storage environment. KSI operates both multi-zone and multi-region environments to maximize uptime and provide the fastest response time to customers.
To prevent unauthorised data access, Keeper's Cloud Security Vault must authenticate each user when transmitting data. Authentication is performed by comparing a PBKDF2-generated hash of the Master Password. The user's device uses PBKDF2 to generate the hash from the Master Password and the server compares the hash to a stored hash.By using the PBKDF2 hash instead of the Master Password itself, the Cloud Security Vault can authenticate the user without requiring the Master Password. By using the same PBKDF2 algorithm for authentication that we do for data encryption, we ensure the strongest level of Master Password protection.
KSI supports 256-bit and 128-bit SSL to encrypt all data transport between the client application and KSI's cloud-based storage. This is the same level of encryption trusted by millions of individuals and businesses everyday for web transactions requiring security, such as online banking, online shopping, trading stocks, accessing medical information and filing tax returns.KSI deploys SSL/TLS certificates signed by Digicert using the SHA2 algorithm, the most secure signature algorithm currently offered by commercial certificate authorities. SHA2 is significantly more secure than the more widely used SHA1, which could be exploited due to mathematical weakness identified in the algorithm. SHA2 helps protect against the issuance of counterfeit certificates that could be used by an attacker to impersonate a website.KSI also supports Certificate Transparency (CT), a new initiative by Google to create a publicly auditable record of certificates signed by certificate authorities. CT helps guard against issuance of certificates by unauthorised entities. CT is currently supported in the latest versions of the Chrome web browser. More information about Certificate Transparency can be found at: http://www.certificate-transparency.org/
Keeper's native clients implement HTTP Public Key Pinning (HPKP). HPKP is a security mechanism which allows HTTPS websites to resist impersonation by attackers using fraudulent certificates.
TouchID on iOS devices allows you to access your Keeper vault on your iOS device using your fingerprint. To provide this convenient feature, an unintelligible version of your Master Password is stored in the iOS Keychain. The iOS Keychain item created for this functionality is not designated to synchronize to the iCloud Keychain and thus will not leave your iOS mobile device.It is highly recommended that you use a complex Master Password and enable Multi-factor authentication in order to provide maximum security for your encrypted Keeper Vault. Using TouchID makes it more convenient to use a complex Master Password on your iOS mobile device. It is also recommended that you set a passcode longer than the minimum 4-digits to secure the iOS Keychain.The iOS Keychain is used by iOS and apps to securely store credentials. iOS apps use the iOS Keychain to store a variety of sensitive information, including website passwords, keys, credit card numbers and Apple Pay™ information. Keeper does not use the iOS Keychain to store your Keeper records - all Keeper records are protected with 256-bit AES encryption and are securely stored in the Keeper Vault. The iOS Keychain is also encrypted with 256-bit AES encryption using the device's passcode. Even if the device is lost or stolen or an attacker obtains physical access to the mobile device, they will be unable to access any stored Keeper information. The iOS Keychain cannot be decrypted without the passcode and the Keeper Vault cannot be decrypted without the user's Keeper Master Password.
The Apple Watch Favourite feature allows the viewing of selected records on a paired Apple Watch. Keeper records must be explicitly enabled to allow viewing on the Apple Watch. A paired Apple Watch communicates with the Keeper Watch Extension that transparently runs in a sandboxed space separate from the iOS Keeper App. The Keeper Watch Extension also uses iOS Keychain to securely store and access keys to enable it to seamlessly and securely communicate with the iOS Keeper app.
Keeper DNA is a new and innovative addition to multi-factor authentication. When used with a paired Apple Watch, Keeper DNA provides a multi-factor authentication method that is unparalleled in convenience and security. Keeper DNA uses secure tokens stored in the Keeper Vault to generate time-based codes for multi-factor authentication. These time-based authentication requests can be approved and sent automatically from the Apple Watch with a tap on the screen of the watch or entered manually by the user. Multiple layers of encryption, TouchID and multi-factor authentication help make Keeper DNA the most elegant, secure and advanced authentication method available.
BreachWatch is a secure add-on service which monitors the dark web for compromised credentials. Currently tracking over a billion known passwords, BreachWatch is continuously adding new information as breaches are discovered on the dark web. BreachWatch is a Zero Knowledge architecture that uses a number of layered techniques to protect our customer’s information. In summary:1. A secure, keyed, cryptographic hash function and anonymization are used to perform a comparison of passwords against a database of breached account information.2. Customer passwords are processed with a hardware security module (HSM) and a non-exportable secret key before being checked against breached passwords or stored on BreachWatch servers.3. Keeper customers interact with BreachWatch using anonymized BreachWatch IDs that are unlinked from other Keeper customer identifiers.4. BreachWatch separates usernames and passwords into separate services with distinct, anonymized IDs to unlink usernames and domains from passwords.5. BreachWatch customers never upload domain information; only downloading domains (the most secure way to perform private information retrieval).To build a secure service, Keeper split BreachWatch into three services; one each for checking domains, usernames, and passwords. Keeper client applications contact each of these backend services using an encrypted REST API.Domain CheckingBreachWatch customers download a list of domains that have been breached and perform the checking locally. Periodically, clients download updated lists of new domains as they are added to our BreachWatch service.Username and Password CheckingClient devices connect to BreachWatch servers and upload a list of hashed usernames (or passwords) along with a client-selected, random identifier (separate identifiers for the username- and password-checking services). These password hashes are processed on upload with HMAC using a hardware security module (HSM) and a secret key stored in the HSM marked as non-exportable (meaning the HSM will only process the HMAC locally and the key cannot be extracted). These HMAC’d inputs (usernames or passwords) are compared against the breach datasets which have been processed with the same HMAC and key. Any matches are reported to the client device. Any values that don’t match are stored alongside the client’s anonymized ID.As new breached usernames and passwords are added to the system, they are processed with HMAC on the HSM, added to the BreachWatch dataset, and compared against the stored client values. Any matches queue a message for that client ID.Clients check-in periodically to BreachWatch and present their BreachWatch IDs. Any queued messages are downloaded and clients upload any new or changed usernames and passwords which are processed the same way.Security of the BreachWatch services is trust-on-first-use (TOFU). That is, clients must assume that the BreachWatch server is not malicious (that is, not actively compromised by an attacker) when the client uploads their hashed values. Once these values are processed with an HSM they are secured against offline cracking attempts. In other words, if an attacker steals the dataset of stored client values, she cannot crack those values offline without the HMAC key stored in the HSM.
