One-time passwords are generated on demand by a dedicated OATH OTP authenticator that encapsulates a secret that was previously shared with the verifier. Using the authenticator, the claimant generates an OTP using a cryptographic method. The verifier also generates an OTP using the same cryptographic method. If the two OTP values match, the verifier can conclude that the claimant possesses the shared secret.
