Turn off your iPhone completely, wait a few seconds, and turn it back on to clear active memory and temporary system errors.

3
Reinstall the App

If the problem persists, press and hold the Microsoft Authenticator icon, tap 'Remove App', and delete it. Re-download the app from the App Store.

Reconfigure Account

Open the newly installed app and follow the prompts to add your work or school account again before attempting the Teams sign-in.

Frequently Asked Questions

Why does Microsoft Authenticator require number matching?

Number matching is a security enhancement designed to prevent MFA fatigue attacks. It requires the user to actively verify the login request by entering the specific number shown on the sign-in screen into their authenticator app.

Can I use another authentication method if the number pad doesn't appear?

Yes, if your organization's IT administrator has enabled alternative methods. You can usually tap 'Sign in another way' on the login screen to receive a verification code via SMS, phone call, or email.

Will reinstalling the Authenticator app delete my linked accounts?

Yes, deleting the Microsoft Authenticator app typically removes the account bindings. When you reinstall it, you will need to re-register your device using a QR code or setup link provided by your organization.
