A one-time password (OTP) is a password that is only valid for a single login session or transaction (usually along a normal static password). Using them reduces risks associated with login into your system from unsecure (keylogged) workstations.

PAM module enables (for example) OpenSSH to do an authentication using
one-time password with the information from user state file. Instead of using passcards one can also configure OTPasswd to send passcode over a secure channel (like SMS).

The program is written in C (C99) and implements OTP as described in
"Perfect Paper Passwords v3". OTPasswd also kind of extends this idea with "salt". Program shares all main ideas with ppp-pam project. It tries to extend it and fix it's deficiencies.
