View 
User interface view 
Parameter 
password: Performs local password authentication. 
scheme: Performs local or remote authentication of username and password. 
none: Log in without authentication. 
Description 
Use the authentication-mode command to configure the authentication method for 
login user. 
Use the authentication-mode none command to configure no authentication. 
This command with the password parameter indicates to perform local password 
authentication, that is, you need to configure a login password using the set 
authentication password { cipher | simple } password command. 
This command with the scheme parameter indicates to perform authentication of local 
or remote username and password. The type of the authentication depends on your 
configuration. For detailed information, see “Security” section. 
By default, terminal authentication is not required for local users log in via the Console 
port. However, password authentication is required for local users and remote Modem 
users to log in via the AUX port, and for Telnet users and VTY users to log in through 
Ethernet port. 
Note: If the Console port is configured for local password authentication, the user can 
directly log in to the system even without a password configured; if other user interfaces, 
such as the AUX port and VTY interface, are configured for local password 
authentication, users cannot log in to the system without a password. 
Example 
# Configure local password authentication.
