The purpose of using multi-factor authentication (MFA) is to enhance security by requiring users to provide multiple forms of verification before accessing accounts or systems. Beyond just a password, MFA typically combines something the user knows (e.g., a password), something they have (e.g., a smartphone or security token), and something they are (e.g., biometric verification). This layered approach adds additional barriers against unauthorized access, significantly reducing the risk of data breaches and account compromise. Implementing MFA is considered a best practice in safeguarding sensitive information.
