There are two ways to configure the YubiKey PAM module to authenticate users. Either via the YubiCloud or using challenge-response. The YubiCloud is the standard method but depends on Yubico's cloud to validate your OTPs and hence requires constant internet access.

The setup is as follows: install the PAM module, register a YubiKey with your user account, create base configuration for either of the two authentication options and then choose the PAM configuration you want to use the YubiKey with.

Local system authentication uses https://www.redhat.com/sysadmin/pluggable-authentication-modules-pam[Pluggable Authentication Modules (PAM)]. You have two options here: pam_yubico and pam_u2f. The former is required for YubiKeys without FIDO2/U2F. If your key supports the FIDO2 standard depends on firmware and hardware model.
