The official Proton Pass extension

Good feature set without subscription. Passkey (!) and passwort management cross-device - on mobile and PC. Aliases, categories - brilliant!

It's okay, but also has a lot of issues:
- the extension does not support security keys
- the extension does not connect to the desktop app. So you have to use a short PIN and data is not available when you have no internet (example: login to your router when internet is offline.)
- the settings for the extension need to be re-configured on every new browser (or profile) you install. Again, and again, and again, you get the same stupid wizzard, because all prior configured settings were forgotten.)

This password manager from Proton is the easiest, most intuitive, user-friendly PM I've found. I've used several in the past, both paid and free. None compare with Proton. It's so user friendly that I'm even going to switch my husband over to it from LastPass (wink!).
