Multi-Factor Authentication (MFA)

About

Multi-Factor Authentication (MFA) is a security technology that enhances the protection of digital systems by requiring users to provide multiple forms of verification to access resources. Unlike traditional methods that rely solely on a username and password, MFA combines two or more independent credentials to verify a user's identity. These credentials can include something the user knows (e.g., password), something the user has (e.g., security token), and something the user is (e.g., biometric data). MFA significantly reduces the risk of unauthorized access by making it more difficult for attackers to breach systems. Even if one factor is compromised, additional barriers must be overcome. Common MFA methods include one-time passwords sent via SMS or email, physical tokens, and biometric verification. By requiring multiple forms of evidence, MFA protects against common threats like phishing and brute-force attacks, making it a crucial component of identity and access management strategies.
