Changing the admin password of a router is one of the important methods with the help of which a user can escalate the security level of the routerlogin.net interface. An ideal password must contain uppercase and lowercase letters, numbers, or symbols. The passphrase must be 30 characters and must not contain any dictionary words from any language over the world. A new password should only be known by trusted users. The password field of the login window is case-sensitive, so for example you are assigning PASSWORD96 as a login password it won’t be the same as the password96.
