Add or remove trusted devices on Mac
A trusted device is a Mac, iPhone, iPad, iPod touch, or Apple Watch that you’ve already signed in to using two-factor authentication. When you sign in on a different device or browser, your device displays a code that you can use to verify your identity. You can add or remove trusted devices on your Mac.
Tip: To manage your trusted devices on another Apple device or on the web, see the Apple Support article Check your Apple ID device list to find where you’re signed in.
Add a trusted device
To make a Mac (macOS 10.11 or later), an iOS device (iOS 9), or an iPadOS device a trusted device, you must sign in using your Apple ID on the Mac or device.
Add a Mac (macOS 13 or later): Choose Apple menu > System Settings, then click “Sign in with your Apple ID” at the top of the sidebar. Enter your Apple ID (or a phone number or email associated with your Apple ID), then follow the onscreen instructions.
Add a Mac (macOS 10.15, macOS 11, or macOS 12): Choose Apple menu > System Preferences, then click Sign In and enter your Apple ID. Follow the onscreen instructions.

You won’t be asked for a verification code again on that device unless you sign out of your Apple ID completely, erase your device, or need to change your password for security reasons.
