Microsoft Authenticator is a popular security application used to generate verification codes and approve sign-in requests for Microsoft accounts, work or school accounts, and many third-party services. When upgrading to a new phone, one of the most important tasks is transferring your authenticator accounts so you do not lose access to two-factor authentication (2FA) protected services.
Moving Microsoft Authenticator to a new phone is usually straightforward if cloud backup was enabled on the old device. The app can restore most Microsoft accounts and many saved authenticator entries automatically. If cloud backup was not enabled, you may need to manually reconfigure your accounts using backup codes, recovery methods, or QR codes from each service.
This guide explains several methods to move Microsoft Authenticator to a new Android or iPhone safely and avoid losing access to important accounts.
Method 1: Check Whether Cloud Backup Is Enabled on the Old Phone
Before switching devices, verify that Microsoft Authenticator backup is enabled on the current phone.
On Android:
- Open Microsoft Authenticator.
- Tap the menu icon.
- Select Settings.
- Locate Cloud Backup.
- Ensure it is turned on.
On iPhone:
- Open Microsoft Authenticator.
- Tap Settings.
- Locate iCloud Backup.
- Verify it is enabled.
Allow the backup process to complete before moving to the new device.
Having a current backup significantly simplifies the migration process.
Method 2: Install Microsoft Authenticator on the New Phone
The next step is installing the app on the replacement device.
To do this:
- Open the app store on the new phone.
- Search for Microsoft Authenticator.
- Download and install the application.
- Launch the app.
You are now ready to restore your backed-up accounts.
Method 3: Restore Authenticator Backup on the New Phone
If backup was enabled previously, Microsoft Authenticator can restore your data.
To restore:
- Open Microsoft Authenticator on the new phone.
- Select Begin Recovery or Restore From Backup.
- Sign in using the same Microsoft account used for the backup.
- Complete any verification prompts.
The application will restore supported accounts from the cloud backup.
After restoration:
- Review all listed accounts.
- Verify they appear correctly.
This is the easiest and most reliable migration method.
Method 4: Reconnect Microsoft Personal Accounts
Although account entries may restore automatically, some Microsoft accounts require re-verification on the new device.
To reconnect:
- Open Microsoft Authenticator.
- Select the restored Microsoft account.
- Follow any prompts requesting approval or sign-in verification.
- Complete the authentication process.
After successful verification:
- Push notifications should function normally.
- Authentication codes will continue working.
This step helps ensure sign-in approvals are properly linked to the new phone.
Method 5: Re-register Work or School Accounts
Accounts managed through organizations often require additional configuration after restoration.
To reconnect a work or school account:
- Open Microsoft Authenticator.
- Select the account.
- Follow the organization’s verification instructions.
- Sign in using your work or school credentials.
- Complete multi-factor authentication setup if requested.
Some organizations require administrators to approve new devices before authentication becomes active.
If verification fails, contact your IT department.
Method 6: Manually Transfer Accounts Without Backup
If cloud backup was not enabled on the old phone, accounts must usually be added manually.
For each account:
- Sign in to the service website.
- Open security settings.
- Locate two-factor authentication settings.
- Choose to add or replace an authenticator app.
- Scan the displayed QR code using Microsoft Authenticator on the new phone.
Repeat this process for every protected account.
Common examples include:
- Email services
- Social media platforms
- Banking applications
- Password managers
- Cloud storage services
Manual transfer takes longer but works reliably when no backup exists.
Method 7: Use Backup Codes If Access Problems Occur
Many online services provide recovery or backup codes when two-factor authentication is enabled.
If you cannot access an account:
- Locate previously saved recovery codes.
- Sign in using a backup code.
- Remove the old authenticator configuration.
- Configure Microsoft Authenticator on the new device.
Backup codes are extremely valuable when replacing phones or recovering from device loss.
Store them securely whenever possible.
Method 8: Verify All Accounts Before Resetting the Old Phone
Before erasing or trading in the old device, confirm that every account works correctly on the new phone.
For each account:
- Attempt a login.
- Generate a verification code.
- Approve a push notification if supported.
- Confirm successful authentication.
Verify:
- Microsoft accounts
- Work accounts
- Email accounts
- Banking services
- Password managers
- Social media accounts
Only proceed with device reset after confirming all accounts function properly.
Method 9: Remove Authenticator Access From the Old Phone
Once the migration is complete, remove unnecessary access associated with the old device.
For Microsoft accounts:
- Open your account security settings.
- Review trusted devices.
- Remove unused devices if necessary.
For organizational accounts:
- Review registered authentication methods.
- Remove the old device entry if it remains listed.
This reduces potential security risks associated with retired devices.
Method 10: Reset or Sell the Old Phone Safely
After confirming successful migration:
- Back up personal data.
- Sign out of accounts.
- Remove security locks.
- Perform a factory reset.
To reset the phone:
- Open device Settings.
- Select reset options.
- Choose Factory Data Reset.
- Confirm the action.
This removes personal information before the device is sold, recycled, or given away.

Final Thoughts
Moving Microsoft Authenticator to a new phone is an important step when upgrading devices because it protects access to accounts secured with two-factor authentication. The easiest approach is to enable Cloud Backup or iCloud Backup on the old phone and restore the backup on the new device. This allows Microsoft Authenticator to recover supported accounts with minimal effort.
If no backup exists, accounts can still be transferred manually by reconfiguring two-factor authentication settings and scanning new QR codes. Regardless of the method used, always verify every account before erasing the old phone and keep recovery codes available in case of unexpected problems. By following the methods outlined in this guide, you can safely move Microsoft Authenticator to a new phone while maintaining uninterrupted access to your important accounts.
