# Replay Password Key

DES key for decrypting the basic authentication password in the session.

(From AM 7.5) Setting this property in the AM admin UI is deprecated; any values set in the AM admin UI are ignored. The value of the DES key is inherited from the secret mapped to the AM secret label `am.authentication.replaypassword.key`.

Default: Empty
