Microsoft Authenticator is getting a preview on Apple Watch for seamless use on iOS. The app will let users approve Sign-Ins, display the notification for approval on the watch face.

“We heard our customers loud and clear—they want support for the Microsoft Authenticator app on Apple Watch,” said Alex Simons, director of program management, Microsoft identity division. “So, that’s why I’m thrilled to announce we are starting to roll out the public preview of the Microsoft Authenticator companion app for Apple Watch.”

Simmons expects the functionality to reach general availability within the next few weeks, letting users avoid PINs and fingerprints. It will work on all supported Microsoft services, including Outlook, across personal, work , and school accounts.

First, though, users will have to download v6.0.0+ on their phone and set up push notifications. To use it now, you’ll have to become a TestFlight user,  which is a relatively simple process.

A Change of Face

For Microsoft, this move signals a willingness to move past Windows 10 Mobile. The company has become more open this year, rolling apps out and implementing mirroring with Windows.

Apple Watch is easily the most popular offering, taking almost half of all sales in the fourth quarter of 2016 and shipping 8 million in a quarter a year later. Analysts expect the industry to grow considerably over the next two years and this is the perfect platform for Microsoft to start with.
