Impossible to enable unlock with Biometrics on Arc browser.

It looks like whatever I do I can’t connect the browser extension to the desktop app, in order to enable Biometrics.

Browser: Arc, updated to last version
Extension: updated to last version (2025.5.0)
Desktop app: updated to last version (2025.5.0)
OS: MacOS 15.5

It used to work several months ago.

When I try to enable Unlock with biometrics I get an error from the extension saying that the permission is not provided:

Looking at the extension details in arc shot that the permission is given:

.

While inspecting the bitwarden service worker when trying to enable the unlock with biometrics I see these logs:

I’ve tried restarting, un-installing, etc.
Touch ID is enabled and working fine within the desktop app.
“Allow Browser integration” is enabled in the desktop app.

Does anyone knows how to do fix?

@oltreseba Welcome to the forum!

The browser extensions do ask for “permissions” when biometrics get enabled… Did you also try to delete the local storage of the browser extension after deinstalling it?In theory, it should ask for the permission again then (after reinstalling it)…
