Apple introduced two-factor authentication to its iCloud and Apple ID login today, adding a layer of security that was proven missing after Wired reporter Mat Honan’s iCloud account was broken into last year.
Two-factor authentication makes your accounts more secure because it’s just an added defense between your information and the bad guys. Some forms of two-factor authentication require that you have a separate dongle that flashes different security codes to enter before accessing your account. Others, such as Google Authenticator, generate these codes on an app on your phone, and others like Facebook send a text message with the code.
