...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.

...keysniffer was initially written with the US keyboard (and conforming laptops) in mind. By default it shows human-readable strings for the keys pressed. However, as keyboards evolved, more keys got added. So the module now supports a module parameter codes which shows the keycode shift_mask pair in hex (codes=1) or decimal (codes=2). You can lookup the keycodes in /usr/include/linux/input-event-codes.h. The keypress logs are recorded in debugfs as long as the module is loaded. Only root or sudoers can read the log. The module name has been camouflaged to blend-in with other kernel modules. ...
