With watchOS 6, the Apple Watch gains the ability to become a trusted device to be used for Apple ID authentication purposes. The new functionality is shown in the below tweet from Jeremy Horowitz.
The Apple ID Verification Code functionality has been available on iPhones and iPads since iOS 9, and on Macs since OS X El Capitan, for Apple IDs with two-factor authentication enabled.

Whenever an Apple ID holder (or someone else) signs into their account on a new device or web browser, the Apple Watch will automatically alerts them, along with an approximate location of the party logging in. If the login attempt is given the OK, a six-digit verification code is displayed, which is then entered on the new device or browser to authenticate the login.
I know I’ll appreciate it, as every time I login using my Apple ID, I have to go in search of my iPhone or iPad to get the authentication code.
