Microsoft Authenticator

The Microsoft Authenticator APK is an account security app for people who want a second verification step or passwordless sign-in. It can verify Microsoft accounts as well as accounts from other services.

For multi-factor authentication, sign in with your password and then approve a notification in the app or enter a one-time code it generates. The codes work without a network connection and have a 30-second timer. You can add multiple accounts, including non-Microsoft accounts.

Passwordless sign-in lets you access a Microsoft account by entering your username and approving a phone notification. A fingerprint, face recognition or PIN provides another verification step. After signing in, you can access Microsoft services such as Outlook, OneDrive and Office.

For work or school accounts, an organization may require you to register your device through the app. It also supports certificate-based authentication and single sign-on, which can help provide access to other Microsoft apps and services after you have verified your identity.
