Method
The Device supports PAP (Password Authentication Protocol) and
CHAP (Challenge Handshake Authentication Protocol). CHAP is more
secure than PAP; however, PAP is readily available on more platforms.
Use the drop-down list box to select an authentication protocol for
outgoing calls. Options are:
AUTO - Your Device accepts either CHAP or PAP when requested by
this remote node.
PAP - Your Device accepts PAP only.
CHAP - Your Device accepts CHAP only.
MSCHAP - Your Device accepts MSCHAP only. MS-CHAP is the
Microsoft version of the CHAP.
