Understanding Multi-Factor Authentication (MFA) and Its Implementation
In the digital age, securing sensitive data and user accounts has become increasingly important. One of the most effective methods to enhance digital security is Multi-Factor Authentication (MFA). MFA provides an additional layer of protection beyond traditional usernames and passwords, making it significantly harder for unauthorized individuals to access accounts, systems, or data.
What is Multi-Factor Authentication?
Multi-Factor Authentication (MFA) is a security system that requires users to present two or more verification factors to gain access to a resource such as an application, online account, or VPN. Instead of just asking for a username and password, MFA requires additional credentials to confirm a user's identity.
MFA factors generally fall into three main categories:
Something you know – A password, PIN, or security question.
Something you have – A smartphone, security token, or smart card.
