-Noctalia supports fingerprint authentication via PAM. To enable it:
-
-1. **Edit the PAM configuration file** at `~/.config/noctalia/pam/password.conf`
-2. **Uncomment the fingerprint line** by removing the `#`:
-   ```conf
-   auth sufficient pam_fprintd.so max-tries=1
-   auth required pam_unix.so
-   ```
-3. **Install required packages**: `fprintd` and `pam_fprintd`
-4. **Enroll your fingerprint** (if needed): `fprintd-enroll`
-5. **Restart Noctalia** for changes to take effect
-
-After enabling, you can unlock using either your fingerprint or password. The fingerprint will be attempted first (max 1 try), then it falls back to password authentication.
-
-**Note:** The PAM configuration file is created automatically on first launch. If it doesn't exist, restart Noctalia and it will be generated.

+Noctalia now uses the standard <code>/etc/pam.d/login</code> for authentication. If you are unable to unlock your lock screen, make sure this file exists and is properly configured on your system.
+
+On some distributions (such as openSUSE), <code>/etc/pam.d/login</code> may not be present by default. You may need to create it manually or copy it from another distribution. Consult your distribution's documentation for details.
+
+If you have previously used a custom PAM configuration for fingerprint authentication or any other form of authentication, you can now remove it. Noctalia will use the system's default authentication methods as defined in <code>/etc/pam.d/login</code>.
 
-openSUSE in particular does not provide the required /etc/pam.d/login.
