Never used Proton Pass but seeing that it doesn't have a desktop app is a deal breaker for me. I hate having to go to my browser, pull up the extension and search for passwords if I'm just trying to log into another program on my computer.
I do wish Bitwarden was able to recognize when desktop apps are asking for passwords and auto fill logins. Roboform, which I tried previously, could do this but there was a lot of jankiness in other parts of the program.
Also tried Dashlane, which was a great experience in general but unnecessarily expensive when FOSS alternatives exist that can do infinite passwords and multi-device syncing.
