README for pam_nfc ================== pam_nfc is a NFC-based PAM authentication module. Using pam_nfc, you can use NFC (Near Field Communication) cards / tags to authorise users into PAM (Pluggable Authentication Modules). Security consideration ---------------------- Since tag IDs cannot be trusted, you SHOULD not only rely on them to grant access to the machine to users. You SHOULD only consider this PAM module as a convenient way for a user to tell his own machine who he is. Basically, the NFC reader is physically connected to the computer, so if an user has a physical access to the NFC initiator, he also has physical access to the computer, and thus strong authentication is already of no luck.
