Accessing Microsoft Teams using organizational or personal credentials
This is usually an MFA sign-in loop between Teams and Microsoft Authenticator. For a work or school account, the fastest path is:
- On the sign-in screen, check whether Sign in another way is available.
- If another method such as SMS, phone, or email was previously configured, use that to complete sign-in.
- If only Authenticator is available, the account is likely configured to require it.
- In Microsoft Authenticator, verify the app itself is usable.
- Open the app and confirm it launches without errors and the account is listed.
- Make sure notifications are enabled.
- Make sure the app is unlocked.
- Update Microsoft Authenticator to the latest version.
- Check network connectivity by switching between Wi-Fi and mobile data.
- Make sure the device Date & time are correct.
- Restart the device.
- If the app is asking for QR code, PIN, or passkey and the sign-in loop continues, contact the organization’s IT admin or helpdesk and ask them to reset MFA settings or allow re-registration of Microsoft Authenticator.
- This is the standard resolution when the account is stuck in a loop and no alternate verification method is available.
- After the reset, sign in again and set up Authenticator from the beginning by scanning the QR code.
- Before contacting support, send logs from the app if possible.
- In Authenticator, open the top-level menu and select Send feedback.
If this is a personal Microsoft account instead of a work or school account, use Microsoft Support after sending feedback logs.
