I have to say that I am extremly surprised about the functionality in the Proton Apps. At the start I was just trying to get away from Google, and migration of E-Mail and documents went like a charm. Calendar is ok, but Photos are not (using Immich). Now I am also using Authenticator.
But the real easteregg is Proton Pass, which has the same functionality as 1Password. I'll keep office stuff in 1Password, and private in Proton Pass. Setup sharing with family as well.
