As tweeted out by Mary Jo Foley, Microsoft announced today a public preview of the Microsoft Authenticator companion app for Apple Watch. The app is coming to a general release within the next few weeks and will allow you to use your watch to approve sign-in notifications that require a PIN or biometric verification.

You can get started with testing this app once version 6.0.0 of Microsoft Authenticator becomes available for testing for you. We're not seeing this version just yet, but you can also enroll here in TestFlight if you're not already up and running with the public preview. Anyway, once you've got that down, you can follow these steps to proceed:
- Make sure your phone and Watch are paired.
- Open the Microsoft Authenticator app on your Watch.
- Under the account title, tap the Set up button. If there’s no Set up button next to your account, no action is required! You can now approve sign-in notifications on your Watch.
You can see this in action by signing into your Microsoft Account using Microsoft Authenticator. You'll then see a notification on your Watch, and you can easily and quickly approve it.
