Thanks for reaching out to us. 

Please note that the login username/password is the same as the local password when logging into the web management page. It is not the password of TP-Link ID or Wireless Password, but an administrative password created when you set it up at the first time.

If you cannot remember any password, please try default username/password which is admin in lower case, however, if it still doesn't work, please reset the TP-Link device by pressing and holding the reset button/hole of the router until the Power LED binks to reset it, then set it up again from the beginning via web management page or Tether APP.
