Not in my experience. I sign into lots of different systems every day and run Teams on all of them, and I never see any MFA prompts so long as I’m on a managed asset. Every system logs in to Teams automatically just by opening the Teams app.

Now, if you’re talking about a pinned app or SharePoint link or something once you’re in the app, maybe. But default chat and meetings should be the same experience, in terms of authentication workflow for the user, as launching and using Outlook.

Yep. I sign in once when the app is opened (which happens automatically as I’m logged into the computer as my Entra ID) and then am never prompted again until I close and reopen Teams.

Something is misconfigured in the environment, or there is a security policy that is set way too high, or one is scoped incorrectly. It is definitely not the normal or expected user experience.

Teams has a lot of faults, but that one is on your org’s admins and security team. Hopefully for you it’s a mistake and not done intentionally.

Agreed. Sounds like a config problem if the whole org is seeing it.

While I agree the UI needs some work, getting prompted for MFA multiple times a day for just using Teams chat and meetings is not normal.
