Problem signing in with new iPhone 17

If this is a personal Microsoft account, use one of these supported recovery paths:

1. Start with the Sign-in Helper to identify the account issue and get the correct recovery steps.
2. If the Authenticator app is prompting for a password that is no longer known, use Recover your account to reset the password with the email address, phone number, or Skype name used for sign-in.
3. If the password is known but no longer works, use the Sign-in Helper.
4. If the username or email is not recognized, verify the correct email domain and spelling, or try another alias or phone number on the account.
5. If sign-in prompts appear that were not initiated, select Deny.

If this is a work or school account, the recovery path is different:

1. Contact the organization’s IT admin or helpdesk to reset or update the authentication methods.
2. If Authenticator sign-in is failing with a temporary app issue, try these steps in order:
   1. Wait a few moments and try again.
   2. Open Microsoft Authenticator and confirm the app opens normally and the account is listed.
   3. Update Microsoft Authenticator from the device app store.
   4. If the device is managed for work or school, check for updates to Company Portal and confirm the device is compliant.
   5. Restart the device.
3. If the issue continues for a work or school account, contact the IT admin or helpdesk.
