When the 1Password app is enabled, users can select to store certain passwords to their Watch. In my personal experience I’ve added every item listed in my Favorites area of 1Password as they are my most frequently used. 1Password even supports one-time passwords on the Apple Watch. 1Password describes the Watch update in the text below:
1Password 6.5 is available in the App Store as a free download, with a $3/month subscription pricing.
1Password for Apple Watch has been rewritten as a native app to take full advantage of the speed and security of running directly on the watch hardware. We’ve also opened the gates and you can finally add items to your Apple Watch from any vault, including 1Password.com account vaults!
