** Description changed:

  [ Impact ]
  
  No fingerprint errors are exposed on fingerprint login failures.
  
  from journalctl, gdm-fingerprint shows error there after retried 5 times
  of fingerprint login failed, so I open this issue here.
- 
  
  [ Test case ]
  
  1. enroll fingerprint for your right index finger.
  2. logout
  3. login and try login by incorrect finger e.g. middle finger
  4. Each time the wrong finger is used an error is shown
  5. After 3 times retries, an authentication error is shown, suggesting
-    to use another method.
+    to use another method.
  
  [ Regression potential]
  
  Wrong errors are shown during both fingerprint auth and other kinds of 
authentications.
  Password failures aren't properly exposed. Verification can't restart on 
error.
+ 
+ Password authentication doesn't work anymore for users with no enrolled
+ prints (as per LP: #1915570)
