How to secure your Apple ID using two-factor authentication

Are you need to know How to secure your Apple ID using two-factor authentication and how it works? So when using two-factor authentication, your account can only be accessed on devices you trust. The trusted device is an iPhone, iPad, or iPod touch with iOS 9 and later, or a Mac with OS X El Capitan and later

If you want to sign in to a new device for the first time, you’ll need to provide two pieces of information your password and the six-digit verification code that’s automatically displayed on your trusted devices. By entering the code, you’re verifying that you trust the new device. For example, if you have an iPhone and are signing into your account for the first time on a newly purchased Mac, you’ll be prompted to enter your password and the verification code that’s automatically displayed on your iPhone.

Why? because your password alone is no longer enough to access your account, two-factor authentication dramatically improves the security of your Apple ID and all the personal information you store with Apple.

After signed in, you won’t be asked for a verification code on that device again unless you sign out completely, erase the device, or need to change your password for security reasons. When you sign in on the web, you can choose to trust your browser, so you won’t be asked for a verification code the next time you sign in from that computer.
