Multi-Factor Authentication

Multi-Factor Authentication

Multi-factor authentication (MFA) is a security process that requires users to provide two or more verification factors to gain access to a digital account or system. This additional layer of security helps protect against unauthorized access, data breaches, and identity theft.

Types of Multi-Factor Authentication

There are several types of factors that can be used in multi-factor authentication:

1. Something You Know:

This factor includes passwords, PINs, security questions, or other knowledge-based information that only the user should know.

2. Something You Have:

This factor involves physical devices such as smartphones, smart cards, or security tokens that the user possesses.

By combining different types of factors, multi-factor authentication significantly enhances security and reduces the risk of unauthorized access to sensitive information.
