Line 1:
'''Password Authentication Protocol''', sometimes abbreviated '''PAP''', is a simple authentication protocol used to authenticate a user to a remote access server or Internet service provider (ISP). Almost all [[Network operating system|NOS]] remote servers support PAP.
PAP transmits unencrypted [[ASCII]] passwords over the network and is therefore considered insecure. PAP is used as a last resort when the remote access server does not support a stronger authentication protocol.
