Password Authentication Protocol is one of the oldest authentication protocols.

Click on the "Use Password Authentication Protocol(PAP)" button to turn it off.

Put a check in the "Use Password Authentication Protocol (PAP)" check box.

It is more secure than the Password Authentication Protocol (another widely used authentication method) since it does not send passwords in text format.

Pressing this button will use PAP (Password Authentication Protocol) instead of CHAP.

Thus, CHAP provides better security as compared to Password Authentication Protocol (PAP) which is vulnerable for both these reasons.

PAP Does your ISP use the Password Authentication Protocol (PAP)?

Password Authentication Protocol (PAP) One of the many authentication methods that can be used when connecting to an ISP.

Pull down the file menu, select PPP options... and make sure that "Use Password Authentication Protocol (PAP)" is not selected.

In the PPP Options window, ensure there is a cross in the box beside Use Password Authentication Protocol (PAP) then click OK.

PAP stands for Password Authentication Protocol and CHAP stands for Challenge / Handshake Authentication Protocol.

Authentication is available as an option, either with the Password Authentication Protocol (PAP), or the Challenge-Handshake Authentication Protocol (CHAP).

For access security, both Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) are provided for use during connection negotiation.

An integrated, firewall-enabled router augmented by protocols such as Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) is therefore necessary.

PPP has supported EAP since EAP was created as an alternative to the Challenge-Handshake Authentication Protocol (CHAP) and the Password Authentication Protocol (PAP), which were eventually incorporated into EAP.
