Recently I have shared several files using Proton Drive. Each time the Pass extension gave me a strong password, but then Pass suggested that I replace the main Proton account password with the new one, which only protects the shared link.

Pass could be smarter and at least for Proton Drive it can see what the user is doing. It would be better to suggest saving the filename or shared link in Pass, but not changing the main Proton password.

I think Pass can work well with Drive. Saving and sharing passwords with Pass would allow users to benefit from joining the Proton ecosystem.
