Why this selector change? It seems fragile. It wasn't a great selector before
(and it looks like maybe it didn't work? I don't see it in lock_screen.html).
It's also not a great variable name; I don't see any checkboxes in
lock_screen.html, I assume it's for the toggle? A unique id might be a good idea
here also.

Yeah, I noticed it was not working while working on this CL so I tweaked it to
work. Changed to use unique id.

       checkbox.hidden = true;
 
+      // The fingerprint settings on options is always hidden.
+      var fingerprintDiv = lockScreen.root.querySelector('#fingerprintDiv');
+      fingerprintDiv.hidden = true;

       var passwordPrompt = lockScreen.root.
           querySelector('settings-password-prompt-dialog');
       passwordPrompt.addEventListener('close', function() {
