With a FIDO2 stick like the Solo V2 it is possible under Linux to log in by just entering a PIN and tapping the FIDO2 stick. This new type of secure and user-friendly login is made possible by the Pluggable Authentication Module (PAM) for the Universal Second Factor (U2F) for short pam-u2f since version 1.1.0.
The official Fedora pam-u2f package has unfortunately not been updated for a long time and is still on version 1.0.8. Therefore I am providing a current version of the package here.
The repository must first be added for installation. The package can then be installed and used from the new repository.
