APOP
Last modified: Thursday, July 07, 2005 

Short for Authenticated Post Office Protocol, it is similar to the POP protocol except that APOP enables your password to be encrypted while being transmitted over the network. Using POP mail, when you authenticate your username and password in your e-mail client, your password is sent over the network in plain text. If your e-mail client uses APOP, then the password is encrypted while being transmitted. APOP prevents hackers from seeing your password information with sniffer programs.
