By default, Web Admin supports only one user, which is authenticated using a locally stored password. Alternatively, you can use TACACS+ to perform authentication. If TACACS+ is enabled, any user configured on the TACACS+ server—including one having the username root—can log in to Web Admin. When TACACS+ is enabled, existing local users and passwords have no effect on authentication.
- Log in to Web Admin.
