Biometrics for browser extension
It is a security risk to not have biometrics available for the browser extension, as people next to you can see you type both your password or pin if you have auto lock on. Please make this available asap.

Allowing biometric login on the "desktop" version of the Proton Pass app but not for the browser extension is backwards IMHO. The desktop app is limited in its usefulness whereas the browser extension is likely to be used much more frequently given that most people have a limited number of applications locally, but tens if not hundreds of credentials to be used on websites.
It's incredibly annoying and inefficient to have to enter a PIN every time Proton Pass locks instead of just being able to use my fingerprint on my Macbook.
