Login password from GDM is shown in plain text on the VT1 console
I don't which package this applies to, but I believe the best bet is GDM.
This bug has been reported downstream here: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1767918
Steps to reproduce:
- Log-in using X11 login via GDM.
- Use the desktop for a while. (For some reason I cannot reproduce if I login and then restart after a short while). It may help to suspend the machine.
- In Gnome click System menu -> Power Button -> Restart
- Quickly press CTRL-ALT-F1
- I see my login password in plain text in the console. Once I saw the login password repeated twice.
