How to Transfer Microsoft Authenticator to a New Phone (Android & iPhone) – Easy Guide
If you decide to move to a new phone, it's essential that you migrate Microsoft Authenticator so you can continue to access your online accounts seamlessly.
Luckily, Microsoft lets you back up your 2FA (two-factor authentication) account information to a cloud server and then transfer that information to your new device. This tutorial will walk you through the entire process.
There is one important limitation, however: You can only transfer Microsoft Authenticator between phones on the same platform. In other words, you can’t move your accounts from iPhone to Android or vice versa.
