Explanation
The original TACACS protocol uses a simple username and static (fixed) password for authenticating users seeking network access. It was an early AAA protocol used primarily for dial-up access control. Later versions - XTACACS and TACACS+ - added more features, but the base TACACS relies on static credentials. Dynamic passwords (one-time passwords) are associated with newer systems and protocols. 'Symmetric' and 'asymmetric' passwords are not standard authentication terminology in the context of TACACS.
