Overview#

Password Authentication Protocol (PAP) is a password-based authentication protocol used by Point to Point Protocol (PPP) to validate users.

Almost all network Operating System remote servers support Password Authentication Protocol.

Password Authentication Protocol is considered a weak authentication scheme and SHOULD be avoided in general.

Password Authentication Protocol's deficiencies is the fact that it transmits plaintext passwords over the network. Password Authentication Protocol is therefore used only as a last resort when the remote server does not support a stronger scheme such as CHAP or EAP.
