I don't know if GOS can fix this, but I agree with you 100% about usability: I have several profiles that I have to switch between frequently every day for security reasons (work & private) or want to switch between for privacy reasons (profile with Google services and "degoogled" profiles).

A few days ago, biometrics stopped working at all when switching profiles. Profiles and the way you can use them in GrapheneOS are an absolutely great security and privacy feature whose usability is unfortunately significantly limited by the biometrics bug. I also don't want to shorten my password just to make this bug easier or merge profiles to reduce the number of changes.

    treequell Sorry, I wasn't able to find this particular bug in the AOSP issue tracker.

    Could anyone please point one out if it still exists there or perhaps it makes sense to report the issue to Google again if it doesn't?

        traveller Hello, I'm still having the issue even after a few updates from GOS. Whenever I switch profiles, either profile is locked and I have to type the password again (which doesn't make sense because I was on this profile a few moments ago), either the fingerprint doesn't appear and I have to turn off/turn on to see fingerprint.

            I have been on one current GOS install since Android 13, and I did not have any problems until I left my phone in a Faraday bag for awhile and it secure timed reset a few times. Maybe this has to do with it.
            Now, it always defaults to PIN when switching profiles. I found that to get biometric quickly I can slide up and it will allow me to biometric. Same with pressing sleep button, and then waking it up again. Rarely it will put both the pin prompt with the biometric overlayed on top and this works.
            Every once in awhile, it will not give me the biometric prompt at all even if I do the steps above for the Owner profile when I switch out of any profile.

              Freedomain forgot to mention this, I also have the PIN prompt color profile bug described above as well. It switches to a default color then when you refresh the PIN prompt it goes back to the profile's correct PIN profile colors.

                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.
