Q: Is Apple Watch supported for Authenticator on iOS?
A: In the upcoming Authenticator release in January 2023 for iOS, there will be no companion app for watchOS due to it being incompatible with Authenticator security features. This means you won't be able to install or use Authenticator on Apple Watch. We therefore recommend that you delete Authenticator from your Apple Watch. This change only impacts Apple Watch, so you will still be able to use Authenticator on your other devices.
You can still mirror Authenticator notifications from your iPhone to your Apple Watch to get notified of approval requests.
