From Teams - Approval Required but Authentictaor App Alreadu has focus

Rob Bowman 216

This problem seems to have started since I updated my phone to ios15 (it's now at is 15.01)

My organisation has their Office365 configured to require MFA. Previously after I attempted a login on Windows that requires MFA, when I opened the iPhone Authenticator app, it would prompt me for authentication. Now it just sits there. I can manually get a code but this doesn't work so well for the iPhone Teams app.

@Rob Bowman ,

Do you mean that you cannot sign in Microsoft Teams client with the authentication code in iPhone Authenticator app?

It is suggested to contact your IT admin to disable and re-enable MFA for you in Microsoft 365 admin center.

Go to the Microsoft 365 admin center.

Go to Users > Active users.

Click on Multi-factor authentication tab option.

Select your account

Click Disable on the right side and then repeat the steps to re-enable MFA.

As your question is related to Microsoft authenticator, I will add corresponding tag to seek further help. Thanks for your understanding.

Hi Sharon, I don't have access to the AAD. I think you're right - this is a question more for the Authenticator app team. The difference seems to be related to the fact that since iOS15 the App no longer receives focus when Azure AAD requests MFA
