A security mechanism that requires multiple forms of verification to access a system or resource.
Description
Multi-factor authentication (MFA) is a critical component of Non-Human Identity Management, which involves securing systems that are accessed not only by human users but also by automated processes, devices, and applications. MFA enhances security by requiring users to provide two or more verification factors to gain access to a resource, such as an application or a network. These factors typically fall into three categories: something you know (like a password or PIN), something you have (like a smartphone or hardware token), and something you are (like biometric data such as fingerprints or facial recognition). In the context of non-human identities, MFA can help ensure that automated systems, APIs, and other non-human entities are also secured against unauthorized access. By implementing MFA, organizations can significantly reduce the risk of data breaches and unauthorized actions, as it becomes much harder for attackers to gain access even if they compromise one factor of authentication. This layered approach to security is particularly important in today's digital landscape, where threats are increasingly sophisticated.
Examples
- Using a password along with a one-time code sent to a mobile device.
- Requiring a digital certificate in addition to a username and password for API access.
Additional Information
- MFA can be tailored to different risk levels and use cases.
- Regulatory frameworks often mandate the use of MFA for sensitive transactions.
