The decision to grant public access to secure networks made genuine Multi-Factor Authentication (MFA) impossible. MFA, by definition, requires users to possess something tangible, like a digital ID, to confirm their identity alongside something they know, such as a password. However, when public logins were introduced, this critical "have" factor was replaced by Single-Factor Authentication (SFA), which relied solely on transmitted data to guess identity, undermining the entire MFA security model. What was intended to be a revolution in digital security quickly became a global deception.
