Multi-factor authentication (MFA) is an advanced security mechanism that requires two or more verification methods from different categories to authenticate a user’s identity for a login or transaction. This approach is much more secure than single-factor authentication, which only requires a username and password. MFA is designed to protect both the user’s credentials and the resources the user can access.
The key components of MFA are:
The purpose of MFA is multifaceted:
Multi-factor authentication provides a robust security framework by combining multiple authentication factors, making it significantly more challenging for unauthorized parties to breach secure systems or data. This not only helps in safeguarding sensitive information but also plays a crucial role in maintaining user trust and complying with regulatory standards.
