Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) is a security process that requires two separate forms of identification to gain access to an account or system. It combines something the user knows (like a password) with something they have (such as a smartphone app or a physical token). This additional layer of security significantly reduces the risk of unauthorized access.




Use Case

A digital agency implements 2FA to enhance security for its clients’ accounts.


Step 1: User Enrollment

During account creation or security settings configuration, users must enable 2FA. They are prompted to enter their mobile phone number or email to receive a verification code.


Step 2: Authentication Process

When a user attempts to log in, they first enter their username and password. After successful entry, the system sends a unique verification code to the user's registered device via SMS or an authenticator app.


Step 3: Verification

The user receives the verification code and must input it within a specified time frame. If the code is correct, access is granted; if not, the login attempt is denied.


Step 4: Access Control

If the user successfully logs in, they can access their account. By using 2FA, the agency ensures that even if a password is compromised, unauthorized users cannot gain access without the second factor.


Benefits:

  1. Enhanced Security: Protects accounts against password theft and phishing attacks.
  2. User Trust: Increases client confidence in the agency's commitment to security.
  3. Compliance: Meets security standards required for handling sensitive data.

Conclusion: Implementing 2FA is a crucial step for the agency to safeguard its clients’ information and maintain integrity in the digital landscape.
