Multi-factor authentication (MFA) is a security mechanism that requires users to provide two or more verification factors to gain access to a resource, such as an online account. This method enhances security by combining something the user knows (like a password), something the user has (like a smartphone or security token), and something the user is (like a fingerprint or facial recognition). By utilizing multiple factors, MFA significantly reduces the risk of unauthorized access during e-commerce and online transactions.
