Restoring access to Microsoft Authenticator without your phone can be tricky, but here are a few steps you can follow to try to regain access:
- Use a Backup Account Recovery Option: If you set up backup authentication options (like a phone number or alternate email), you can use those to verify your identity and regain access to your account.
- Microsoft Account Recovery: Go to the Microsoft Account Recovery page. You'll need to provide the email address and other details related to your Microsoft account. You'll be asked to verify your identity using any backup methods you might have set up (such as a phone number or email).
- Contact Microsoft Support: If you don’t have any backup options and can't recover your account through the usual methods, you can reach out to Microsoft support. They may be able to assist you in recovering your account and disabling two-factor authentication temporarily so you can set it up again.
- Reinstall and Reconfigure Authenticator: If you can get into your Microsoft account on a computer, you can reinstall the Authenticator app on your new phone and reconfigure it. But you'll need to first disable two-factor authentication temporarily, either through recovery options or support.
I hope this information is helpful to you.
