New Teams - How do you remove users from the "Pick an account" / Login screen?

While testing "New Teams" I have noticed that the "Pick an account" / Login screen shows the previous users that have logged in, even if they have clicked "sign out".

When clicking on those users, it also logs them in without asking for a password.

After reading other posts here, I have tried deleting the cache here: %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe

And also deleting the data in this folder: %LocalAppData%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

Doing this has stopped the accounts from being logged in without a password, but the accounts still appear on the "Pick an account" / Login screen.

They do not show in classic teams or any other application and there are no additional accounts in the "Access Work and School" windows setting page.

I have also tried to fully remove and reinstall Teams but the accounts are still visible.

Does anyone have a solution for this?

Thanks

EDIT:

I have found a possible solution:

Delete:
%LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe
%LocalAppData%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
%LocalAppData%\Microsoft\OneAuth
%LocalAppData%\Microsoft\TokenBroker
%LocalAppData%\Microsoft\IdentityCache

Then restart the PC.

This will sign out all Microsoft products but does remove the users from the login list and removed their login details, meaning a password is required to login to Teams.

    That's easy to achieve with regedit, under

    HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin

    add the the following:

    DWORD: BlockAADWorkplaceJoin
Value: 1

    Hey thanks, Martin! That's awesome. That screen is confusing and annoying and I'd love not to see it!

    Oh, good. If I ever knew about that, I had completely forgotten about it.

    When I looked it up, I was disappointed by Microsoft starting its description of it like this:

    "You can prevent your domain joined device from being Microsoft Entra registered by adding the following registry value..."

    Fortunately, however, that's misleading. It works on mere workgroup PCs, too. I think they probably phrased it like that because it's a common use case where those on a domain might not want to join anything further.

    The problem affects the new Teams desktop client so it might be a good idea to stick to Teams classic version and disable any upgrade to the new Teams client.

    You can still download Teams classic and keep a copy safe in case Microsoft removes all download links https://go.microsoft.com/fwlink/?linkid=2187327

    You should be able to stop any upgrade to the new Teams client using registry hacks. A few are on the internet or a setting within your patch update software

    Always trial on a test computer first.
