Multi-Factor Authentication (MFA) is a security process that requires users to provide two or more verification factors to gain access to an account or system. This method enhances security by combining something the user knows, like a password, with something they have, such as a smartphone or a security token. By requiring multiple forms of identification, MFA makes it more difficult for unauthorized individuals to access sensitive information. MFA is commonly used in various online services, including email accounts and banking applications. It helps protect against cyber threats, such as phishing and identity theft, by adding an extra layer of security. Even if a password is compromised, the additional verification steps can prevent unauthorized access.
