Two-Factor Authentication (2FA) is a security measure that requires two forms of verification before granting access to an account. Typically, this involves something the user knows (like a password) and something the user has (such as a smartphone app or a hardware token). When logging in, after entering the password, the user must provide the second factor, often a code sent via SMS or generated by an authenticator app. This added layer of security helps protect against unauthorized access, even if the password is compromised.
