Two-Factor Authentication (2FA)

What is Two-Factor Authentication (2FA)?

Two-factor authentication is a specific type of multi-factor authentication that requires exactly two different forms of identification to access an account. This usually involves a combination of something the user knows, like a password, and something they have, like a code sent to their mobile device.

Why It Matters

• It adds a critical layer of security that prevents unauthorized access even if a user’s password has been stolen or guessed.

• 2FA is widely available and easy to implement for most online services, making it an accessible security upgrade for all users.

• It significantly reduces the risk of successful account takeovers from phishing and credential stuffing attacks.
