Can the fingerprint sensor store secrets?

I have mine registered and working in Fedora 40. I also tried registering in Windows 11, and it looks like it goes thru, BUT it never actually gives me the option to use the fingerprint as a login option at the login screen.

@Nomad upthread mgiht be able to shed some light. I don’t dualboot so just hearsay on my part.

I enrolled in Fedora 40 and it works fine there. When I enrolled in Win 11, it seems to have accepted the registrations, but when at the login screen, it doesn’t offer a finger print login as an option. Going back to Control Panel it does show it’s still registered. I can delete the registration and try again, but it still doesn’t show up as an option in the actual login screen.

For me it just worked. I did setup Windows first, when everything functioned (simply setting up the fingerprint recognition did it) I installed Fedora and enrolled the fingerprints again.
Everything worked ever since, login in Windows and skipping password prompts on Linux.

Do you still have to unlock the keyring? Or do you not use it?

I finally got it to work. I had to delete the contents of 2 files in C:\Windows\System32\WinBioDatabase and reregister my prints. (Have to stop Windows Biometrics service first, then start it back up after I cleared the file contents).

Doesn’t that happen when login in with the password?

But I’m on Mint (Edge) now and there it doesn’t work at all, fprintd-enroll says “enroll completed” but fprintd-list tells me I have no fingers enrolled :confused:

I thought you said you didn’t enter a password but used the fingerprint reader

Not for login though, only during things like the UAC prompt equivalent of Linux or for sudo in terminal
