Observed behavior

Before you start

Ensure that you are signed in to the correct iCloud account on your iPhone, as Microsoft Authenticator backups for iOS devices are securely stored in your personal iCloud account.

Solution 1Recommended

Verify and Sign In With All Account Aliases

Use this solution if your Microsoft account has multiple email addresses, phone numbers, or Skype names associated with it, which may have been used during the initial backup.

Microsoft Authenticator backups are strictly tied to the specific primary alias that was active when the backup was created. If you have added or changed email addresses on your account, the app might fail to locate the recovery file under your new preferred alias.

1
Check Your Account Aliases Online

Open a web browser, navigate to the Microsoft account login page, and sign in. Go to 'Your info' and select 'Edit account info' to view all email addresses, phone numbers, and Skype names associated with your account.

2
Begin App Recovery

Open the Microsoft Authenticator app on your newly updated iPhone. Do not select 'Add account'. Instead, tap the 'Begin recovery' option at the bottom of the screen.

3
Enter the Correct Alias

Sign in using the exact alias (email, phone, or Skype name) that was primarily used when you initially turned on the backup feature. Repeat this process for each alias if the first attempt fails.

Personal vs. Work Accounts: Personal Microsoft accounts use iCloud for Authenticator backups. If you are using a Business or School account, the recovery process might be different, and you may need to contact your IT administrator.

Frequently Asked Questions

Why is my Authenticator backup missing after an iOS update?

An iOS update itself typically does not delete the backup. However, if the app was reinstalled or app data was reset during the upgrade, you must actively select 'Begin Recovery' and sign in with the exact Microsoft account alias originally used to back up your credentials to iCloud.

Can I restore Microsoft Authenticator directly from an iPhone iCloud backup?

Authenticator account credentials are encrypted and stored in iCloud, but they are not automatically restored when you restore your phone from an iCloud backup. You must open the Authenticator app and use its built-in 'Begin recovery' feature to decrypt and restore the accounts.

What happens if I permanently lose access to my Authenticator backup?

If the backup cannot be recovered, you will need to recover each of your two-factor authentication accounts manually. This typically involves using the alternative verification methods provided by each specific service, such as SMS verification, backup codes, or contacting the support team for those individual accounts.
