MFA (Multi-Factor Authentication) Basics

MFA (Multi-Factor Authentication) is a security measure that requires users to provide two or more verification factors to gain access to a resource such as an application, online account, or VPN. This method enhances security by combining multiple forms of authentication, making it more difficult for unauthorized individuals to access sensitive information. MFA (sometimes known as 2FA) helps to secure your network and keep out unauthorized users by verifying your identity.

Here are the different methods of MFA, along with a short definition of each:

1. Knowledge Factors: These involve something the user knows, such as a password or a PIN. These are among the easiest to implement but are also susceptible to compromise if not backed by other factors.
2. Possession Factors: These rely on something the user possesses, such as a smartphone or a security token. These factors typically work by sending a verification code to the device or using a dedicated app to approve login attempts, adding a layer of physical security.
3. Inherence Factors: These involve something the user is, such as fingerprints, voice recognition, or facial recognition. These biometric methods are more difficult for unauthorized users to replicate.
