No user can interact with the web menu Dashboard of the tplinkwifi.net interface without typing a correct password on the required field of the login window. A user can change the default password when the Tp-link router setup process gets done. Changing the login password frequently escalates the security level and also keeps unauthorized users away from controlling and managing the router. While changing a Wi-fi password, make sure you are fulfilling all the requirements required to assign a login password.
