Display cue message like "Place your finger on the fingerprint reader"

[reesericci]

Is your feature request related to a problem? Please describe.
When I edited the PAM config to use fprintd, the theme doesn't prompt me to place my finger. I press enter, and touch. I would like some kind of alert box displaying the cue message (like in sudo).

Describe the solution you'd like
Add a blue alert (like the red invalid password error) displaying the cue message.

Describe alternatives you've considered
Removing the password box if there is another sufficient login method (like fingerprint)

Additional context
I saw the closed issue about fprintd. I'm asking for fprintd cue messages, not for support to register fingerprints

Feel free to open a pull request if you would like to see this feature implemented, but I don't have the hardware (or the need) to test and maintain this properly myself.
