It does the job and it does it well enough.

I would like the ability to unlock the extention with Touch ID instead of a PIN, just like the desktop app. The Bitwarden extension supports it, so it is feasible.

Doesn't work flawlessly, but then I very much doubt the other password managers do either. 90% of the time Proton Pass works quite well and is especially handy. The other 10% of the time it just doesn't seem to trigger correctly, or it'll only input the username or password instead of both.

Room for improvement, but overall I can't say I haven't been extremely pleased with my experience.

Best extension on earth. Proton is awesome.
