How 2FA Works

Two-Factor Authentication (2FA) enhances security by requiring two distinct forms of identification to verify a user's identity. Here's how it typically works:

1. Login Attempt: You start by entering your username and password on the login page of a website or application.
2. Second Factor Prompt: After entering your credentials, the system prompts you for a second form of verification. This could be:
3. • A code sent to your phone: You receive a one-time code via SMS or an authentication app.
4. • A physical device: You might use a hardware token or a USB security key.
5. • Biometric verification: This could involve scanning your fingerprint, face, or retina
6. Verification: You enter the code or complete the biometric scan. The system verifies this second factor.
7. Access Granted: Once both factors are verified, you gain access to your account.
