I've seen multiple bugs with the lockscreen like this, which makes me wonder whether there can also be bugs that allow to bypass entering PIN and unlock the (previously logged in) profile without entering PIN at all.

    I am a relatively new GOS user and having the same problem with the fingerprint sensor on a Pixel 8 when changing from a user profile to my main profile. It didn't happen from the beginning, but started a few days ago.

    Now I am asking myself if it might be due to the way of changing profiles.

    1. The fingerprint option seems to disappear, if you close the secondary profile from the lock screen.

    2. I am not sure, but it seems to work well, if from within the secondary profile you swipe down twice to show the toggle screen with switches like air plane mode, network, bluettoth, NFC etc and then choose the mainprofile using the switch on the lower right.

    matchboxbananasynergy Nothing fancy, have owner account and 1 secondary user(owner have play services installed and secondary account doesn't have). after switching back to the owner account the fingerprint icon is showing up now and im able to unlock.
    Have you tried creating a new account and test with that just incase. I just created 1 more new user and still its working.

        W1zardK1ng does the secondary account have a fingerprint or not? how are you switching to owner? via end session? have you allowed the secondary profile to run in the background via the toggle?

            matchboxbananasynergy Secondary account have fingerprint and pin. both ending session and switching to owner by clicking the user icon from notification panel is working. run in background is also enabled.

              Issue still occurs for me on a secondary profile with a fingerprint and on one without. It's not consistent, which is why it can't be fixed easily.

                Yes me too! As far as I can tell it was the last bug I could find in my usage, now it runs perfectly!

                  For me it seems to always allow fingerprint unlock if i swap profiles directly to a secondary one or to owner if I'm logged into a profile. same if i end a session and swap to a profile from the owner unlock screen.

                  but if i end a session from a power button press to wake up screen i get no fingerprint promt. same if i switch sessions from a wakeup. really weird.

                  if this happens i can switch back to the profile i came from login there and switch while its logged in and have fingerprints meet me again. if i login to another profile and try it does not work. so something weird is happening here

                  Not to sure on a debug but when it happens and lets me log in.. the finger print shows up for maybe half a second flash to the padlock then stays there for maybe a sec before it allows fingerprint again.

                  QPR2 "Fixed" it for me as well. It stays on the lock icon for a few seconds and after that, SystemUI seems to correct itself. Im using End session.

                  It's now working for me, too. Hopefully someone can find out what exactly fixed it for some people and why other still facing this issue.

                  I still have no fingerprint when switching back to owner , once logged in it works as normal .

                  This has been happening to me too for several weeks. It happens 100% of the time: I am in a secondary profile. I exit my secondary profile by holding down the power button to end session. My owner profile is missing the fingerprint and asks for the full password to enter. Just to note, my secondary profile has no fingerprint, PIN only.

                  It was mentioned in 0321 thread that the bug is marked as closed meaning this will probably never going to be fixed.

                  Can you who don't have this issue write your model, when first installation was and when it became fixed?

                  Has anyone made any full reinstall and saw this issue fixed?

                  I am running Pixel 7 with 0321 version and this still happens to me 100% of the times.
                  The fingerprint sensor shows for 0.2 seconds and then dissappear. Only way to unlock main profile after switch is through passcode always.

                  I tried removing all prints, tried disable, reprogram fingers but issue still persists.

                  Considering the upcoming 2nd factor feature with finger+pin I think this issue should be more prioritized to be fixed.

                    JayJay Looking at the issue report, it was closed as "completed", meaning that it is assumed to be fixed. It was closed after my report, and because there have been no other reports in the issue after that, it is still regarded as fixed. You can make a comment in the issue. Preferably providing info about your device, OS version and any custom configurations that might be applicable.

                      I thought it was fixed (after one recent update I suddenly got fingerprint working whenever I switched profiles, but after another update (or just a reboot?) it stopped working again 100% of times.

                      Could you please post a link to the issue in the issue tracker? May be worth posting some comments there to get some attention to the issue (or trying to fix it ourselves)?
