| CRYPTOcard, Security Dynamics Inc, and Axent are token servers supported by CiscoSecure ACS. CiscoSecure ACS can authenticate using a third party Token server when CiscoSecure ACS is configured as a client to the Token card server. Requests are accepted at the Network Access Server (NAS) then passed to CiscoSecure ACS, which passes the one-time password to the token server for authentication. The Token server sends CiscoSecure ACS an accept or reject message. If approved, access is granted.
