Thank you for taking the time to review our extension Giorgi! Biometrics are harder to implement in a browser extension, although we do support them in the mobile apps. You can protect your extension with a PIN lock though, and we also recently introduced the ability to have a second password for Proton Pass only, for users that deem this more secure.

If you have any further suggestions or feedback, don't hesitate to reach out to us via the 'Feedback & Help' option.
