A system for credential authentication comprises an interface configured to receive a create indication to create a badge credential representing an employee badge and receive a claim indication from an authentication device to claim the badge credential, and a processor configured to provide the badge credential to the authentication device in response to the claim indication, receive a proof response from the authentication device comprising the badge credential and a lock identifier, validate the proof response using a distributed ledger, and provide a token for unlocking a lock associated with the lock identifier to the authentication device.
