Once you enroll the app with an account you want to secure, the app will spit out new codes every 30 seconds. We recommend readers avoid this method if possible because those messages can potentially be intercepted.Ī better option is to use a code-generating authenticator app, such as Authy or Google Authenticator. The most common-and, unfortunately, least secure-is to receive a special code sent via SMS. There are several different ways to implement MFA. When Google required all employees to use MFA, account takeovers dropped to nearly zero. Even if the logins are accepted, they’ll be prompted to enter the second-factor information and will be immediately stymied. With MFA, even if someone has nabbed some or all of your login credentials - say, from a major data breach like the one that happened at LastPass - they won’t be able to access any account secured with MFA. You might see both terms, but they effectively mean the same thing.
This used to be called two-factor authentication (2FA), but with new options emerging all the time, it has been dubbed multi-factor authentication (MFA). To prevent that, security experts now recommend mixing multiple factors.
The problem is that if a bad guy gets ahold of your username and password, they can log in as if they were you and take over your account. Typical username and password login schemes employ just one factor - something you know. Something you have, like a smart device or a hardware security key. Something you are, like a biometric attribute such as your fingerprint. The current thinking on authentication holds that there are three factors you can use to verify your identity: Here are a few tips on how to set it up on Apple devices, courtesy of PCMag’s Max Eddy. Setting up security keys can be critical. But first, it’s important to understand what multi-factor authentication is and why using a security key is one of the best ways to keep your accounts safe.
We’re here to show you how to use a security key to protect your Apple ID. Given how much your Apple ID matters, it’s important to keep it safe from account takeovers, and one of the best ways to do that is with a hardware security key. It grants access to the App Store, FaceTime, Find My, iCloud, and Messages. An Apple ID is a critical piece of information for anyone with an Apple device, be it a laptop, desktop, phone, or tablet.
