The router administrator account is used to log on to the router interface. Usually, the router has a default login name, which is printed on the label on the back of the router. If you can't find the router account in the router body or manual, you don't need this account for your router login.
Router login password?
The router login password is generally printed on the back of the fuselage like the login user name. Some models of routers only have default passwords, such as admin or null or password.
If you don't display the default password on the body and instructions, then your router doesn't have a default password, which is usually created by yourself when the router is initially set up.
If you set the password but forget it, you need to reset the router to the factory settings and set it again.
