I make sure to sign out of proton mail from all devices, and only log in when I need to. I do this to make sure no one has access. Not even my home PC has access to my proton account. It seems unsafe that my proton pass account requires me to leave my proton mail and drive unprotected. Even if you add a pin to your proton pass, your proton mail and drive remain vulnerable, making the pin almost meaningless.

I do like the note taking feature in proton pass. And the UI is quite nice, though I find it a bit frustrating that the Web UI doesn't follow the layout that proton mail and proton drive have in the web UI (For example the settings and user profile are on the top right in mail and drive.... in pass it's on the bottom left for some reason.....) It also doesn't use the same color palette....

EDIT - added 1 star Proton has addressed some of my concerns, though the main security concerns are still there. Looking forward to future improvements.
