The technology often used for authentication in e-commerce is two-factor authentication (2FA). This security measure enhances user account protection by requiring two forms of verification before granting access. Typically, this involves something the user knows, like a password, combined with something they have, such as a mobile device or security token, which generates a unique code. 2FA significantly reduces the risk of unauthorized access and fraud, ensuring that transactions and sensitive information remain secure during the shopping experience. Many e-commerce platforms endorse this method to bolster consumer trust.
