If you haven’t used an authenticator app before, you may have experience with SMS- or email-based two-factor authentication codes. Depending on the app you’re using, you may have to enter a code or tap the “Approve” button. The authentication attempt usually appears as a push notification. Some password managers even offer built-in authenticators with similar functionality.Īfter installing an authenticator app on your phone, you’ll be able to confirm new login attempts without receiving a short message service (SMS), email, or other message. Google Authenticator is a good default, but there are many other apps out there, such as Microsoft Authenticator, Authy, and Duo Mobile. Authenticator AppsĪuthenticator apps are one of the simplest and most reliable methods of two-factor authentication or multifactor authentication.
Your options depend on the specific website or app you’re using. In this section, we’ll go over some of the most common factors in 2023. There are many forms of authentication used to verify login attempts alongside passwords. Generally, a higher number of factors lead to better security since a hacker would have to compromise every single factor to get into the account. For example, five-factor authentication means that the user needs five different factors to log in. The phrase “X-factor authentication” refers to an authentication process that requires a certain number of factors. A hacker can log in simply by acquiring your password, which makes your accounts relatively vulnerable. The password is the only factor required to complete the authentication practice. If your accounts are secured by a password alone, you’re technically using single-factor authentication. By guessing, stealing, or otherwise gaining usernames and passwords, hackers can perform the traditional authentication and find a way into your account. More than 60% of all breaches stem from compromised credentials. Unfortunately, passwords are far from foolproof on their own. As long as you’re the only person who knows your password, entering the password is enough to authenticate the login attempt. Passwords are the most straightforward authentication method for online accounts. To understand the difference between 2FA and MFA, you first need to understand the words “factor” and “authentication.”Īuthentication is all about confirming that the right person is logging into a particular account. That’s because they both refer to the number of factors used to authenticate a given access attempt. Aside from “two” and “multi,” you’ll notice that these terms are exactly the same.
