How to Transfer Microsoft Authenticator to a New Phone Without Losing Access

At Louisville Geek’s 24/7 Help Desk, one of the most common calls we receive is:

“I just upgraded my phone, and now I can’t log in because my Microsoft Authenticator app isn’t working!”

If you’re a Louisville Geek client, this is great news. You have unlimited access to our team and we’ll get you back online quickly. There’s an even better option though. You can avoid the problem altogether by enabling cloud backup before you switch devices.

What Happens When You Don’t Back Up Microsoft Authenticator?

Microsoft Authenticator is essential for Multi-Factor Authentication (MFA) security. When you upgrade your phone, the app doesn’t automatically transfer your accounts unless you’ve turned on cloud backup. Without it, you’ll need to reconfigure MFA for every account, which is a process that often requires IT support.

How to Back Up Microsoft Authenticator Before Switching Phones

Follow these steps to make your next phone upgrade stress-free:

1. Open the Microsoft Authenticator app on your current phone.
2. Tap the Settings (gear icon).
3. Turn on Cloud Backup (iOS) or Cloud Sync (Android).
4. Sign in with your Microsoft account to complete the setup.

When you install Authenticator on your new phone, you’ll be able to restore your accounts in just a few taps.

Already Upgraded Your Phone Without Backing Up?

Don’t worry, that’s what we’re here for! Our 24/7 Help Desk can:

• Reset your MFA settings.
• Walk you through re-registering your accounts.
• Ensure your security is fully restored.

Pro Tip: Check Other Accounts

Authenticator isn’t just for Microsoft accounts. If you use it for banking, social media, or other apps, check if those accounts support backup or export. Otherwise, you’ll need to reconfigure them too.
