Approve App Authentication Requests with Your Apple Watch in Catalina

Tired of typing your admin account password whenever you try to install software or change security settings on your Mac? A new feature in macOS 10.15 Catalina removes that requirement for Apple Watch owners. In System Preferences > Security & Privacy > General, select the checkbox for “Use your Apple Watch to unlock apps and your Mac.” Then, whenever an app asks for your account credentials, you can instead just double-press the side button on your Apple Watch. Of course, if you forgot to wear it or its battery has died, you can always fall back on entering your password.
