Console login authentication modes
The following authentication modes are available for console port login: none, password, and scheme.
none—requires no username and password at the next login through the console port. This mode is insecure.
password—requires password authentication at the next login through the console port. Keep your password.
scheme—requires username and password authentication at the next login through the console port. Authentication falls into local authentication and remote authentication. To use local authentication, configure a local user and related parameters. To use remote authentication, configure the username and password on the remote authentication server. For more information about authentication modes and parameters, see the Security Configuration Guide.
