|  |  | When TACACS+ is used with CiscoSecure ACS, it has the ability to configure password aging with a warning period; provide functionality for remote access, reject easy-to-guess passwords, and change user passwords. Message catalogs are available in many languages, including French, Japanese, and English. TACACS+ also provides support for a single TCP connection between CiscoSecure ACS and the Network Access Server (NAS), creating higher performance.
