Windows Hello auths but doesn't unlock vault

I’ve been having an issue with Windows Hello unlock not actually unlocking Bitwarden after a successful auth. It’s happening in both the chrome browser extension and the Windows desktop application.

It’s not 100% failure rate, maybe 80-90%.

With the browser extension there’s a tell when it will work. When the Hello dialog opens inside/over the extension it will work. If it opens un parented, usually backgrounded, then it won’t.

Example of failure mode:

For the desktop there’s no such tell, it reliably opens the dialog in front.

In both cases when it works, it tends to work for a little while before failing again. For example whilst testing to write this, browser has failed 5-6x no success, desktop failed 2-3 times until I went into settings to be 100% it was enabled and now it’s working.

When it fails, it always successfully completed the windows hello auth process shows my name and OK to continue. But the vault stays locked.

Hello and welcome to the community :waving_hand:

It might be helpful if you report the versions of both clients — the About > Copy button should do it.

Also noting this is about face/camera biometrics, since fingerprint biometrics skips the “OK” confirmation dialog.

Oops sorry of course I should have added versions:

Desktop:

Version 2026.3.1
SDK ‘main (7637fdf)’
Shell 39.2.6
Renderer 142.0.7444.226
Node 22.21.1
Architecture x64

Extension:

Version: 2026.4.0

SDK: ‘main (aaccd8d)’

Server version: 2026.4.1

Both should be latest as much as I can tell.
