Microsoft Authenticator: Backup not restore

Question

I have changed my old iPhone to a new iPhone. When signing in with MFA to recover the backup, it doesn't sync with the new phone. Why is that?

Answer 1

You must sign with same Apple ID on both devices.

Verify that iCloud Backup is enabled and MFA data is included there.

Two-factor authentication settings are consistent on both the devices.

Check App settings.

Reinstall MFA. Sign out and sign in into MFA.

Shutdown and restart both the devices.
