Apple ID dual authentication can greatly improve security. Here’s how to turn on dual authentication in Mac OS Big Sur system.
Significance of dual authentication
Double authentication means ensuring that only you can access your account, even if others know your password.
With dual authentication, your account can only be accessed through devices you trust, such as iPhone, iPad, or Mac. When you log in to a new device for the first time, you need to provide two kinds of information: your password and the six digit verification code automatically displayed on your trusted device. After entering the verification code, you confirm that you trust the new device. For example, if you have an iPhone and want to log in to your account for the first time on a newly purchased Mac, you will be prompted to enter your password and the verification code automatically displayed on your iPhone.
Because you can no longer access your account by entering only your password, dual authentication significantly enhances the security of Apple ID and all personal information stored through apple. After logging in, the system will not ask you to enter the verification code on the device again unless you completely quit the login account, erase the device data, or need to change the password for security reasons. When you log in on the web, you can choose to trust your browser, so that the next time you log in from this computer, you will not be asked to enter the verification code.
