I just ran into the same behavior. I typed my password quickly and automatically into the lock/login screen... and was disturbed to see the whole thing right there in plaintext as I was hitting enter.
I poked at it a bit, and here's a reproducer: * Go to the lock/login screen. * Right-click on the password input field. You get a little popup menu. * One of the options is "Show Text". If you choose that option, the password input now shows in plain text. I'm pretty sure I wasn't anywhere near the mouse when I originally saw this behavior, so I suppose there's some keyboard sequence that invokes the same option. I must have mashed that as I was getting the screen to wake up. I see why this feature could sometimes be useful when encountering an unfamiliar keyboard layout, etc. But triggering it by accident is pretty startling; so I'd love to set an option to make it impossible to trigger. I can't find such an issue in the GNOME configuration, but I'm not at all confident the places I was able to find to look in are comprehensive. There's an issue upstream (in gnome-shell) where someone asked for such an option: https://bugzilla.redhat.com/show_bug.cgi?id=1506370 Also an older bug report where others ran into this behavior by accident (the reproducer someone found there was helpful to my finding a reproducer, though that exact sequence doesn't do it for me on gnome-shell 3.28): https://bugzilla.redhat.com/show_bug.cgi?id=1178806 There's even a RH Knowledge Base article for the question of how to disable it! https://access.redhat.com/solutions/3224961 That's marked "Solution Verified", which sure sounds like there is a way... but without a Red Hat subscription, I can't see what it says. The open gnome-shell issue sure makes it sound like there isn't one. ** Bug watch added: Red Hat Bugzilla #1506370 https://bugzilla.redhat.com/show_bug.cgi?id=1506370 ** Bug watch added: Red Hat Bugzilla #1178806 https://bugzilla.redhat.com/show_bug.cgi?id=1178806 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772791 Title: Lock Screen displayed password in clear text on one occasion To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1772791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
