On a Face ID-equipped device, this means signing in with Face ID, while other devices, including Touch Bar-capable MacBook Pros, use Touch ID. When you visit iCloud in Safari on a device running the iOS, iPadOS, or macOS betas, you’ll see a new pop-up asking if you’d like to sign-in using your Apple ID with biometrics. When you head to on a device running the betas, you can now sign-in to your account using Face ID or Touch ID.
For iOS 13, iPadOS 13, and macOS Catalina beta testers, Apple is trying out a new sign-in process for iCloud on the web.
