A Simple Guide to Creating a Microsoft Authenticator Backup

A straightforward guide to protecting your access before something goes wrong.

Authenticator apps are brilliant for keeping your online accounts secure—but what happens if your phone is lost, stolen or damaged?

Without access to those six-digit codes, getting back into your business systems, emails and other important accounts can become extremely stressful and time-consuming.

This guide walks you through creating a backup of your Microsoft Authenticator account on a second device, giving you an additional way to access your authentication codes if something happens to your main phone.

Inside, you’ll learn:

• why relying on only one device can leave you vulnerable;
• how Microsoft Authenticator backups work;
• how to prepare your original account;
• how to restore the backup onto a second device;
• and how to keep your spare device protected and updated.

I recommend using an older smartphone that can remain safely at home as your backup device.

This guide forms part of the Simple Guides collection—practical, jargon-free resources designed to make the technology behind your business feel more manageable.

Please remember that apps and device settings can change over time. Always check Microsoft’s current instructions and choose the security setup that feels right for you.
