Account passwords used for Tekron clocks are are not stored on nor transferred to the clocks at all, and password encryption is not reversible. All user account passwords are encrypted using the mechanism described in RFC-3414 for the User-based Security Model (USM) in Simple Network Management Protocol (SNMP), where the password is combined with the unique clock identifier before being hashed by the client. The hashes used for the passwords are unique to each and every clock, regardless of whether the password used is the same.
