How to Fix Microsoft Authenticator Codes Not Showing?

Microsoft Authenticator may fail to show verification codes on a new device due to an incomplete backup restore, platform mismatch, unfinished cloud sync, or device and app settings that interfere with time-based one-time passwords.

Main Causes

• Backup not restored because the restore prompt was skipped or existing accounts were already present in the app.
• Platform mismatch when an iOS backup is used on Android or vice versa.
• Cloud sync incomplete even if backup shows as enabled.
• System conflicts such as disabled notifications, incorrect time settings, outdated app/OS, or restricted network conditions.
• No backup or missing source device, which requires resetting MFA from the Microsoft Security Info portal or through admin tools.

To resolve this issue, you need to restore your Authenticator backup or re-add the app as a sign-in method. The following steps explain how to do this in detail.

Solution: Recover or Re-add Microsoft Authenticator

The most reliable way to fix this problem is by restoring the Authenticator backup or reconfiguring the app on your new device. Follow the steps below:

Step 1: Enable Cloud Backup (Old Device)

1. Tap the menu dots in the top right corner.
   
2. Select Settings.
   
3. Scroll to the Backup section and enable Cloud Backup.
   

Step 2: Restore Backup on New Device

1. Install Authenticator from your device’s app store.
   
2. Open the app without signing in. Tap Restore from backup > Begin recovery.
   
   
3. Sign in with the Microsoft account where the backup is stored.
   
4. Refresh the app to confirm that codes appear.

Step 3: Re-add Authenticator if Backup Fails

1. Sign in to your Microsoft account in a browser.
2. Go to the Security tab in the left sidebar.
   
3. Click Manage how I sign in.
4. Locate Send sign in notification (Authenticator option) and select Remove. Confirm the deletion.
   
5. Click Add a new way to sign in.
   
6. Select Use an app.
   
7. Follow the prompts until a QR code appears, then scan it with your new device.
   
8. After scanning, your account will be restored and codes will display.

For organization accounts, contact your admin if options are restricted. If none of these steps work, contact Microsoft Support for account recovery assistance.
