I personal think that separate apps are preferable so that you can use only what parts of the proton suite you want to - An installer that lets you select from all of the proton apps that you'd like to have installed would be preferable to a monolithic app.

(Maybe a metapackage with all the apps for linux package repos in whatever packing guideline proton provides to linux packagers.)

On the sign-in to multiple apps issue - maybe some kind of integration with OS level keyrings to store proton session tokens so you only need to login once, except pass that should probably be kept separate.

I've moved my services to proton cause of wide range of offerings (mail,password etc). Now we have dedicated desktop apps for mail and pass (really appreciated) but we have to keep all apps separately.
Since you don't need anything apart from proton in your services, what about one for all desktop app?

E.g
-Mail as main app
- "Pass" button that requires additional pin on click, but without separate app
- Quick VPN button on main window
- Quick "drive access" button on main button
- SimpleLogin quick access in one app

So rather than having mail,drive,pass and vpn as separate apps, and simple login as browser extension (unless you have pass plus) , we could have one to rule them all app.

I would like to open one app/window sign in via ubi or otp 2fa whichever you prefer and have access to mail,drive, pass , any and all future. Proton products. Preferably this would be available for download via opensource github fdriod ect.

Hello,

When reinstalling my computer, I needed to reinstall every app drive, bridge, vpn… and each time I had to do the full logging process.

I was wonderingif it was possible to develop one Proton software with all the feature inside.

Maybe the same also in mobile device app …

Thanking you very much
