Two-factor authentication may soon be superseded by a new solution that involves a cryptographically verified phone number and various security factors, such as a network verified mobile number, IP address, SIM card attributes, phone number tenure, and phone account type. Advanced analytics and machine learning capabilities will also be part of the protection scheme.



AT&T, Verizon, Sprint, and T-Mobile joined together to create the Mobile Authentication Task Force. Their goal was to cook up a new and improved security solution for their devices. They announced Thursday at the 2018 Mobile World Congress that their solution will undergo trial testing in the coming weeks and might be available by the end of the year.
