A two-factor bypass is a security exploit where an attacker circumvents or defeats a two-factor authentication (2FA) mechanism, thereby gaining unauthorized access to an account or system despite its implementation. This can occur through various methods, including SIM swap attacks, sophisticated phishing schemes, or vulnerabilities within the 2FA system itself. Such a bypass severely compromises account security. It effectively negates an essential layer of protection.
Context
News reports often detail instances of two-factor bypass attacks targeting cryptocurrency exchange accounts or digital wallets, frequently leading to significant asset theft. These incidents underscore the ongoing need for users to employ robust 2FA methods, such as hardware security keys, and for platforms to continuously strengthen their 2FA implementations. The battle against these bypass techniques is constant.
