Multi-factor authentication (MFA) is an access management tool designed to harden user authentication when accessing IT systems. At its core, MFA hardens traditional password-based access by introducing additional authentication factors. A multi-layered approach is required for users to log in successfully.
Users must authenticate themselves using something they know, such as a password or security question answer; something they possess, which could range from hardware tokens or codes from authenticator apps like Google Authenticator and Duo Mobile app to FIDO security keys; and something they are, which typically includes biometric factors like facial scans or fingerprints.
In this article, we will discover more about multi-factor authentication and how it is implemented into our daily lives, and we will discover how managed service providers are simplifying the integration of an MFA provider into businesses like yours.
What Is Multi-Factor Authentication (MFA)?
Multi-factor authentication (MFA) is a robust authentication method that requires users to provide multiple verification forms before granting access to a system or account. Instead of relying solely on passwords, which are vulnerable to theft or breaches, MFA adds layers of security by combining two or more authentication factors.
These authentication factors can be:
- Knowledge: Something the user knows, like a password.
- Possession: Something the user has, such as hardware tokens or push notifications to cell phones
- Inherence: Biometric factors, such as fingerprints or facial recognition.
By requiring multiple forms of authentication, MFA solutions significantly reduce the risk of unauthorized access caused by stolen credentials, weak passwords, or system vulnerabilities. Even if a malicious actor were to gain one factor, like a password, they would be obstructed without the other required elements.
Many modern identity management systems incorporate MFA as a fundamental feature. For instance, Azure Active Directory supports conditional access policies that trigger MFA in response to suspicious user activity. Plus, authentication logs record any authentication attempts, allowing administrators to monitor and act upon any unusual patterns.
Authentication providers, such as Ping Identity, Duo Security, and Cisco Secure Access, offer dedicated MFA solutions that integrate with existing infrastructure, enhancing access security and user authentication processes. They provide additional functionalities like adaptive authentication, which adjusts authentication methods based on active risk assessments.
