- Something You Are: This involves biometric factors, such as fingerprints, facial recognition, or even voice patterns. It adds another layer of security thatâs unique to each person.
Each of these factors functions cohesively, enhancing security by making unauthorized access significantly harder.
Authentication Flow Explained
The flow of authentication in a two-factor system follows a simple yet effective path:
- User Initiation: You, the user, begin by entering your username and password on a site or app.
- Prompt for Second Factor: After recognizing your credentials, the platform prompts you for the second factor, like a unique code generated or sent to you.
- Verification of Second Factor: You provide the second factorâthis could be entering a code or scanning a fingerprint or face.
- Access Granted: If both factors are verified successfully, you gain access to your account.
This layered approach not only fortifies security but gives gamers and cybersport athletes the assurance that their accounts are less prone to intrusion amidst frequent online competitions.
