User Identity Management 27

By default, no user is set on the router. In this case, the user can log onto the router without username and password, operating as the administrator user and have the right to execute all commands.

The router should be configured with at least one administrator user. This is because any user can log onto the router as the administrator user if no user is set on the router which could lead to a breach in network security.

If a user is configured on the router, no matter what type of user they are, when that user logs onto the router, it will prompt them to input the username and password. Only after the username and password are input correctly can the user log onto the router, and the system will give the user the corresponding access rights.

The router can only be configured with the operator user and guest user after an administrator user has been configured.

If an operator user forgets their password, the administrator user can help them to modify the password. Also, they can enter into the boot menu (only on the HyperTerminal connected to the Console port) to clear the application password, and then reboot the router. At this time, the operator user can log onto the router without username and password.

If an administrator user forgets their password, they can modify the password through another administrator user identity. If there is no other administrator user, they can only enter into the boot menu (only on the HyperTerminal connected to the Console port) to clear the application password, and then reboot the router. In this case, the router will restore the default configuration, that is, no user is set on the router. Because the operation clears the configuration, the administrator must reconfigure all the functions and parameters.
