Two-Factor Authentication (TFA) Protocol enhances security by requiring two separate forms of verification before granting access to an account. This method significantly reduces the chances of unauthorized access.The first factor typically involves something the user knows, such as a password. The second factor adds an extra layer of security, often based on something the user possesses, like a smartphone. For example, after entering the password, the user might receive a text message with a code that must be entered to complete the login.Implementing TFA helps protect against various threats, such as phishing attacks and password theft. Even if a password is compromised, an attacker would still need the second authentication factor to gain access.Many platforms that deal with transactions and personal data encourage or require TFA for this reason. Users are urged to enable this feature, as it is a simple yet effective way to enhance their account security.
