No user can interact with the web interface of a Tp-link range extender without entering the login credentials on the Tp-link extender login window. A user can change the default login password during the setup process. In most cases, users are recommended to change the default password as it will secure the tplinkrepeater.net window from anonymous users. You can enable the password recovery feature so that if you forget the login password you can restore it using the web interface of the Tp-link range extender.
