Cyber threats are an ever-evolving reality, making strong security measures vital for both personal and organizational data integrity.

How 2FA Works

At its core, 2FA works by requiring two forms of verification before granting access to an account or system. This usually includes something the user knows, like a password, and something the user has, typically a code generated by an application or a text message. Here's how the process generally flows:

User Login: The user enters their username and password.
Second Factor Request: Upon successful entry, the system prompts the user for a second factor of identification, usually a code.
Code Generation: The user then receives this code either through an SMS, via an authenticator app, or through a hardware token.
Code Verification: The user inputs the code back into the system, which checks it against the expected value.
Access Granted or Denied: If everything checks out, access is granted. If not, the user is halted at the door, forced to reassess their entered credentials.
