libpam-google-authenticator - 20191231-2 main

The Google Authenticator project includes implementations of one-time
passcode generators for several mobile platforms, as well as a
pluggable authentication module (PAM). One-time passcodes are generated
using open standards developed by the Initiative for Open
Authentication (OATH) (which is unrelated to OAuth).
.
These implementations support the HMAC-Based One-time Password (HOTP)
algorithm specified in RFC 4226 and the Time-based One-time Password
(TOTP) algorithm currently in draft.
