Is PAP still used?

Almost all network operating systems support PPP with PAP, as do most network access servers. PAP is also used in PPPoE, for authenticating DSL users. As the Point-to-Point Protocol (PPP) sends data unencrypted and “in the clear”, PAP is vulnerable to any attacker who can observe the PPP session.

Does radius accept PAP?

PAP. PAP, or Password Authentication Protocol, is the least secure option available for RADIUS. RADIUS servers expect any password sent via PAP to be encrypted in a particular way that is not considered secure.

Which is better PAP or CHAP?

CHAP is a stronger authentication method than PAP, because the secret is not transmitted over the link, and because it provides protection against repeated attacks during the life of the link. As a result, if both PAP and CHAP authentication are enabled, CHAP authentication is always performed first.
