Two-factor authentication (2FA) is a security measure that requires users to provide two forms of identification in order to access an account. The first form of identification is typically a password, while the second form is a unique code generated by an authentication app. This added layer of security helps to protect against unauthorized access, even if a password is stolen or guessed.
Authenticator apps are widely available for both iOS and Android devices, and many of the most popular apps are completely free to use. In this article, we will take a look at some of the best authenticator apps available for enhanced security.
