Starting in watchOS 6, the Apple Watch has become a trusted device for Apple ID authentication purposes.

When you or someone else signs in to your Apple ID on a new device or browser, the Apple Watch will automatically alert you, complete with an approximate location of the person. If the sign-in attempt is allowed, a six-digit verification code will then appear to be entered on the new device or browser.

This functionality has been available on iPhones and iPads since iOS 9, and on Macs since OS X El Capitan, for Apple ID accounts with two-factor authentication enabled. Now, users simply have one more option in the Apple Watch.
