AAL1 provides basic confidence that the claimant controls an authenticator that is bound to the subscriber account. AAL1 requires either single-factor or multi-factor authentication using a wide range of available authentication technologies. Verifiers SHOULD make multi-factor authentication options available at AAL1 and encourage their use. Successful authentication requires that the claimant prove possession and control of the authenticator through a secure authentication protocol.
