1. Two-factor authentication (2FA) adds an extra layer of security to the authentication process by requiring users to provide two different forms of verification before accessing their accounts. This helps prevent unauthorized access even if a password is lost or stolen. Here's how 2FA prevents unauthorized access in the case of lost or stolen passwords: - Verification Factors: Two-factor authentication typically combines something the user knows (such as a password) with something the user has (such as a mobile device). When a user logs in with their password, the second factor is required for authentication. This second factor is usually a unique code or token that is sent to the user's mobile device or generated through an authenticator app. - Mobile Device as Second Factor: In the case of lost or stolen passwords, an attacker would still require the second factor, which is often linked to the user's mobile device. This adds an extra barrier for unauthorized access. Ev...
