A current biometric sample is obtained from a user requesting access to a secure resource, together with a user identifier and a current token code. A bio-hash value that encodes a distinct biometric identifier of the authentic user for the user identifier, combined with the authentic user's PIN, is retrieved. A computed PIN is generated based on biometric information extracted from the current biometric sample and the bio-hash value. The computed PIN is combined with the current token code to generate a one-time passcode. The one-time passcode and the user identifier are conveyed to an external user identity verification process that uses the one-time passcode to validate the computed PIN and current token code contained in the one-time passcode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Personal identification number (PIN) replacement in a one-time passcode based two factor authentication system","description":"Biometric information is used to generate a one-time passcode in a two factor authentication process.
