While the app's iOS update with version number 6.7.3 states that it "removes Microsoft Authenticator from Apple Watch ", it also states that you can continue to mirror any Microsoft Authenticator notifications you receive on your iPhone to your Apple Watch.
Microsoft first made Authenticator available for the Apple Watch in 2018, and it has proven useful for anyone looking to streamline multi-factor authentication (MFA) sign-ins. Instead of opening the Microsoft Authenticator app on your phone to verify your identity, you could confirm sign-in via a notification that appeared on your watch.
We first heard about the Apple Watch app shutdown last December, after Microsoft quietly updated its FAQ page to state that you can't install or use Authenticator on the Apple Watch. It's unclear why Microsoft has now chosen to drop support for the Apple Watch, but it vaguely states that watchOS is "incompatible with Authenticator security features."
watchOS over the past few years; It has lost a number of notable apps like Pokémon Go , Uber , Instagram , and more. In fact, this proves that not every service has to be on your wrist. However, among all these applications, Microsoft Authenticator was one of the most practical applications, so having it turned off will upset some users.
