I saw the threads about the Firefox extension not working with biometrics, but I get it in Windows.
When Bitwarden starts, it’s supposed to ask me for my fingerprint, however I never get the Windows Hello windows.
However, after I’ve entered my master password and I’ve logged into BW, THEN the Hello WIndo opens.
As for the plugin, it doesn’ work with Hello on Firefox, Brave, and probably the others, too. I haven’t tested all my browsers.
