To be able to add, as on Thunderbird, several Proton accounts in the same Linux desktop app (I'm not talking about alias, or the ability to easily switch between two accounts). I need to see simultaneously, all my accounts in the same window. As I know, the beta version can only be used for one account.

In Proton Mail for iOS, I can easily switch between my different accounts (personal and professional). In Proton Calendar for iOS, I can only access one of those accounts. I sometimes miss appointments or create scheduling conflicts because of not being able to easily check both calendars.

It's important now more than ever to get this feature working.

For some reason the request for multiple account logins on Proton Calendar for Android/iOShas been merged with this general protonmail for PC request.

very important and basic feature

This feature is important for anyone who logs in to multiple accounts which I think is a significant portion of the users. The log out and then log in with a new user method is a bit more clunky feeling and being able to check email from a different account from browser, phone app, or desktop using a "switch account" AND "switch address" (because multiple addresses can be under one account) would be preferred.

This would be a very welcome feature.

Currently, the ProtonMail Windows desktop application can only use one ProtonMail account. It would be good to be able to log in with several ProtonMail accounts, and do more in the same way in the ProtonMail web user interface.

Adding another voice to this. I am another of the multiple-paid-accounts group. I'm in the Apple ecosystem so that's my focus but this should be everywhere.

Please give us multi-account login. I have more than one (paid) Proton account and I can't log into all of them simultaneously via the OSX Proton Mail app. Mail is my first pain point but I need this in all your products.

This is super critical - especially for those who use/want to use Proton for business and personal - would also love to be able to log into multiple accounts for all the other proton apps both on mobile and desktop (MacOS). Need to be able to get to drive for business and drive for personal. Would like to be able to all all proton accounts to native Mac OS apps as well.

Need account switching between personal and business accounts too in MacOS proton app.

How is this not getting more attention?

We need the ability to log into multiple calendars simultaneously on mobile!

Skiff sunsets on August 19 and we need Proton to have this capability by then!

The ability to switch between user accounts on Desktop Mail and Cal app would be useful (to me at least).

Besides my private account I share one account with my wife for mutual mailing and calendar functionality.

Functionality to switch accounts like in the web browser is what we need! :-)

In short: the ability to switch between accounts without logging on-and-off all the time.

I have multiple paid Proton Mail Accounts. I recently started using the Proton Mail application for Linux. There should be a easy switch option between accounts. At the moment I can only sign in on 1 account at a time

Logging into multiple accounts on the mail app is great. I would also love to be able to log into multiple accounts for all the other proton apps both on mobile and desktop.

Absolutely this is needed.
you can log in to multiple email accounts via the android mobile app, but you can't log into more than one account with the calendar app.

With the demise of Skiff, people who want to move secondary accounts over to Proton may not in the end, as you can't log in to a second calendar in the app.

Please implement it!

Yes, this is essential when you want to separate Work and Private accounts. I really hope this will be a possibility soon!

The thing that makes me want this feature is the following:
I have 2 accounts for which I want to see the calendar. This can be achieved by sharing the calendar of one account with the other and have edit rights.

But if I want to invite someone with the other account for an event, I cannot do that. It makes sense, as an email should be sent with the other account and I only have the rights to the calendar.

Being able to log in to both accounts in the calendar app would resolve this issue.

I am in the process of setting up over 100 Proton Family Accounts this would be extremely useful for these clients to be able to switch accounts like they can in Protonmail now. Thank You
