3 Authenticator and Verifier Requirements

This section is normative.

This section provides detailed requirements that are specific to each type of authenticator. With the exception of the reauthentication requirements specified in Sec. 2 and the requirement for phishing resistance at AAL3 described in Sec. 3.2.5, the technical requirements for each authenticator type are the same, regardless of the AAL at which the authenticator is used.

In federated applications described in [SP800-63C], the authentication functions of an IdP correspond closely with that of a CSP or verifier. In the discussion below, the requirements associated with a CSP also apply to an IdP.

In many circumstances, subscribers need to share devices that are used in authentication processes, such as a family phone that receives OTPs. In public-facing applications, CSPs SHOULD NOT prevent a device from being registered as an authenticator by multiple subscribers. However, they MAY establish restrictions to prevent large-scale fraud or misuse (e.g., limiting the total number of subscriber accounts a single device can be registered with).

Authentication, authenticator binding (discussed in Sec. 4.1), and session management (discussed in Sec. 5) are based on proof of possession of one or more types of secrets, as shown in Table 2.

Table 2. Summary of secrets (non-normative)

Type of Secret Purpose Reference Section
Password A subscriber-chosen secret used as an authentication factor 3.1.1
Look-up secret A secret issued by a verifier and used only once to prove possession of the secret 3.1.2
Out-of-band secret A short-lived secret generated by a verifier and independently sent to a subscriber’s device to verify its possession 3.1.3
One-time passcodes (OTP) A secret generated by an authenticator and used only once to prove possession of the authenticator 3.1.4, 3.1.5
Activation secret A password that is used locally as an activation factor for a multi-factor authenticator 3.2.10
Long-term authenticator secret A secret embedded in a physical authenticator to allow it to function for authentication 4.1
Recovery code A secret issued to the subscriber to allow them to recover an account at which they are no longer able to authenticate 4.2
Session secret A secret issued by the verifier at authentication and used to establish the continuity of authenticated sessions 5.1
