Introducing the updated Microsoft Authenticator! One app to quickly and securely verify your identity online, for all of your accounts. This app provides an extra layer of protection when you sign in, often referred to as two-step verification or multi-factor authentication. If you’ve enabled this for your Microsoft accounts, you’ll get a notification from this app after trying to sign in. Just tap approve and you’re good to go. For any other account, or if you’re offline, our built-in security code generator has got you covered. New features and updated app design are only available if you have completed the Windows 10 Anniversary update. Without the update, you will receive an older version of the app which only supports two-step verification for work and school accounts. This new app replaces the Azure Authenticator, Microsoft account, and Multi-Factor Authentication apps.
