Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is a security system that requires more than one method of authentication from independent categories of credentials to verify the user's identity for a login or other transaction. MFA is an effective defense against unauthorized access, including hacking and identity theft, because it adds multiple layers of security, making it more difficult for an unauthorized person to gain access to a device or network.
The essential elements of MFA involve at least two of the following three categories:
MFA is commonly used in both personal and business applications, significantly enhancing security by combining these factors. If one factor is compromised or broken, an attacker still has at least one more barrier to breach before successfully breaking into the target. This method is especially critical in protecting sensitive data and systems and is increasingly used in areas like online banking, email services, and during any transaction that requires high security to protect user data.
By implementing MFA, organizations can reduce the likelihood of network attacks and data breaches, providing a higher level of trust and confidence for both users and providers in the security of the transactions.
