Was using BitWarden, which is fantastic. But since Proton Pass came out, I wanted to try it since I already switched to use Proton Mail and Calendar. I like the idea of having "all my things in one place" (as long as it's a good place).
Both the app and the extension look good and simple. Exporting json from BW into PP had no issues and I have already used it on a couple of sites. I give 4 stars since just comes out (at least publicly) and devs don't get high on success and keep improving it :P but I can recommend!
