I just recently downloaded the Proton Pass desktop app for Linux, but every time I close the app it logs me out. It would be a great feature for the desktop app to have a Pin enabled unlock feature like my LibreWolf browser extension has. It's easier for me to open a new browser and use the pin to unlock Proton Pass than it is for me to open the desk top and go through a full log in + 2FA session on my home computer. This pin unlock feature would be very handy, especially if you could have a pin unlock on the Proton Mail desktop app as well, for the same reasons.
