In the case of PPP, a user name (and in conjunction with PAP, CHAP or MS-CHAP, a password) is sent to the remote station when the connection is established. When a computer dials into the device, the communications software, for example Windows Dial-Up Network, prompts the user for the user name and password.
If the router establishes the connection itself, for instance, to an ISP, it uses the user name and password from the PPP list. If no user name is entered there, the device name is used instead.

In addition, the PPP protocol also permits the caller to require an authentication from the remote station. The caller then requests a user or device name and password from the remote station.
