3.1.7.3 Usage With Subscriber-Controlled Wallets

A specific form of multi-factor cryptographic authentication is a subscriber-controlled wallet on the subscriber’s device, as described in Sec. 5 of [SP800-63C]. After the claimant first unlocks the wallet using an activation factor, the authentication process uses a federation protocol, as detailed in [SP800-63C]. The assertion contents and presentation requirements of the federation protocol provide the security characteristics required of cryptographic authenticators. As such, subscriber-controlled wallets on the subscriber’s device can be considered multi-factor authenticators through the activation factor and the presentation and validation of an assertion generated by the wallet.

Cloud-hosted wallets are not considered cryptographic multi-factor authenticators because access is maintained through authentication over the internet rather than locally. All authentication information from hosted wallets is treated as an assertion, as addressed in Sec. 5 of [SP800-63C].

Access to the private key SHALL require an activation factor. Authenticator activation secrets SHALL meet the requirements of Sec. 3.2.10. Biometric activation factors SHALL meet the requirements of Sec. 3.2.3, including limits on the number of consecutive authentication failures. The password or biometric sample used for activation and any biometric data derived from the biometric sample SHALL be erased immediately after an authentication transaction.

Authentication processes using subscriber-controlled wallets SHALL be used with a federation process as detailed in Sec. 5 of [SP800-63C]. Signed audience-restricted assertions that are generated by subscriber-controlled wallets are considered phishing-resistant because they prevent an assertion presented to an impostor RP from being used by the legitimate one. Assertions that lack a valid signature from the wallet or an audience restriction SHALL NOT be considered phishing-resistant. Assertions SHALL also include sufficient information to determine the nature of the activation method used to activate the wallet.
