MFA is crucial for protecting sensitive information and preventing unauthorized access to resources. The current adoption rate of MFA is under 40% in small businesses, highlighting the need for its implementation. MFA requires users to provide two or more verification factors, which can include something they know (password), something they have (authenticator app or SMS), or something they are (biometric verification). Leveraging a combination of these factors creates strong security measures that reduce the risk of unauthorized access while maintaining user experience. MFA is essential in scenarios involving sensitive information, remote access, compliance requirements, and high-profile accounts. However, its implementation continues to evolve with new technologies and methodologies, such as biometrics, AI, and machine learning.
