Microsoft first introduced password-free sign-ins to its accounts with an Authenticator app for iOS and Android last year. The app lets you approve requests to sign into a Microsoft Account without a password. Microsoft is now extending this same functionality to a new Apple Watch app so you can approve sign-ins straight from your wrist.
The app will let Microsoft Account users approve requests that typically require a password, PIN, or biometric authentication straight from an Apple Watch. Push notifications will appear on the Watch, and Microsoft Account users just select the number that’s shown in the sign-in screen to approve the request. It’s easy to setup straight from an Apple Watch, and if you’re already a Microsoft Authenticator user then you can easily move personal and work accounts from your iPhone over to a watch.
Microsoft is trialing this initially in public preview, and plans to make it available to everyone within the next few weeks. Microsoft Authenticator is limited to personal (Outlook.com) accounts and work-related accounts like Office 365.
