I use it everyday for a few years now and love it. Only problem I ever had was, a few weeks back, I had to keep loggin-in twice every time because it wouldn't show my keys on my first attempt. Now it looks like they've patched this bug, so no problems anymore.

Won't accept log in credentials. Asks for PC password, but rejects it. Useless.

EDIT: I suddenly got it to work by checking the "Require verification for browser integration" setting, setting up Biometrics in the Firefox extension, and then after logging in, unchecking the setting again. Now it works every time. Weird why this was necessary.
The biometrics integration stopped working recently, which very much sucks.

Menu cannot be exited in Firefox Mobile. Cannot return to browser without restarting. This doesn't happen always but very often. Unfortunately mostly unusable.

Bitwarden is a fantastic password manager. It's independently audited and the free is very much feature complete. The premium is cheap at one dollar per month at the time of writing and very much worth it to me. Looking forward to the android app rewrite and the widespread adoption of passkeys.
