Proton Pass Security in it's Global Settings could have some general and session overviews regarding all of the Pass instances and apps, such as the browser extensions.

Now, there is separation in each Pass app-specific settings by design as confirmed by Proton Staff to be intentional, sure, but we need one place, one app (webapp or the desktop windows app?) that's considered the main or primary one that should have some global overview, security and session management of all the Proton Pass instances to get a sense how many extensions and sessions are active (or used in past)

It can get crowded and perhaps confusing when you're a power user with multiple web browsers and even versions of the same, portable editions, on many different PCs, windows, linux, android, multiple smartphones, tablets, can be very useful to get some better security overview, perhaps logs, but also being able to revoke sessions.

What if I lose my phone or a device, I'd just revoke session, without having to at worst change the password for the whole proton account.

Some session and login management is already in the webapp for the general protonmail, but it's still more tied to the main and mail accounts without good indication/separation, because mail was the first and main product so this is understandable.
