 ## Enabling fingerprint for system authentication
-To enable fingerprint login, if it doesn't come automatically, run
-```
-$ sudo pam-auth-update
-```
-and use the space-bar to enable fingerprint authentication.
-The change will take effect immediately. At this point, the fingerprint
-will be tried first, and only if that fails or times out will you see
-a password prompt. Take note of the led-stripe above the fingerprint
-sensor to see whether it is active.
 
-### The actual change from pam-auth-update
+if it doesn't come automatically, you might need to make changes to files in `/etc/pam.d` to enable fingerprint login (depending on your distro).
-The above mentioned command `$ sudo pam-auth-update` simply makes a small modification to /etc/pam.d/common-auth:
 
-```
+- On Fedora, use `authselect`[^1]:
-# In /etc/pam.d/common-auth, the following line is added, and the next line changed.
+  ```
-# The end result (apart from other things that may be in the file) is this:
+  $ sudo authselect current
-auth  [success=2 default=ignore]  pam_fprintd.so max_tries=1 timeout=10 # debug
+  $ sudo authselect enable-feature with-fingerprint
-auth  [success=1 default=ignore]  pam_unix.so nullok_secure try_first_pass
+  $ sudo authselect apply-changes
-```
+  ```
+
+- On other distros, run
+  ```
+  $ sudo pam-auth-update
+  ```
+  and use the space-bar to enable fingerprint authentication.
+  The change will take effect immediately. At this point, the fingerprint
+  will be tried first, and only if that fails or times out will you see
+  a password prompt. Take note of the led-stripe above the fingerprint
+  sensor to see whether it is active.
+
+  You can also take a look at [Configuration: fprint](https://wiki.archlinux.org/title/Fprint#Configuration) on the Arch Wiki for an idea how the file should be modified.
