Google Authenticator PAM Library
Example PAM module demonstrating two-factor authentication
...A lightweight enrollment program bootstraps each account by generating a secret, printing a QR code, and writing per-user configuration with safe file permissions. Because verification happens locally, codes work offline and do not depend on any Google service, which suits high-security and air-gapped environments. Administrators can tune skew tolerance, rate limiting, emergency scratch codes, and which PAM control flags enforce 2FA for specific users or groups. The project’s design favors simplicity and auditability, keeping the runtime small and the configuration explicit so it’s easy to review in production change control.
