About Microsoft Authenticator

Microsoft Authenticator is a phone app for Android and iOS that adds a second verification step when signing in to online accounts. It supports passwordless sign-in for Microsoft accounts and for work accounts managed through Microsoft's identity services.

It suits people whose employer uses Microsoft Entra sign-in, and anyone with a Microsoft account who wants to approve sign-ins from a phone instead of typing a password each time.
