If your system includes a fingerprint reader, you can use biometric authentication in addition to standard authentication via login and password. After registering their fingerprint, users can log in to the system either by swiping a finger on the fingerprint reader or by typing in a password. openSUSE® supports most available fingerprint readers. For a list of supported devices, please refer to http://reactivated.net/fprint/wiki/Supported_devices.
If the hardware check detects the fingerprint reader integrated with your
laptop (or connected to your system), the packages
libfprint
,
pam_fp
, and
yast2-fingerprint-reader
are automatically installed.
Currently, only one fingerprint per user can be registered. The user's
fingerprint data is stored to
/home/
.

The PAM module pam_fp
supports fingerprint
authentication for the following applications and actions (although you
may not be prompted to swipe your finger in all cases):
Logging in to GDM/KDM or a login shell
Unlocking your screen on the GNOME/KDE desktop
Starting YaST and the YaST modules
Starting an application with root
permission:
sudo or gnomesu
Changing to a different user identity with su or
su -
username

If you want to use a fingerprint reader device, you must not use encrypted home directories (see Kapitel Verwalten von Benutzern mit YaST (↑Referenz) for more information). Otherwise logging in will fail, because decrypting during login is not possible in combination with an active fingerprint reader device. |
