Two-Factor Authentication Breaks Free from the Desktop

Two-factor authentication (2FA) is expanding beyond traditional IT systems into physical environments, particularly in the automotive and healthcare industries. Car thieves are using relay attacks and key cloning to bypass existing security, prompting companies like Keyfree Technologies to develop 2FA solutions combining hardware and mobile apps. Auto companies are exploring biometrics, ultra-wideband digital keys, and PIN-to-drive models, though usability and lack of standards remain barriers. In healthcare, medical devices like dialysis machines and infusion pumps are increasingly requiring 2FA or MFA to protect sensitive patient data and prevent unauthorized access with real-world safety consequences. Experts warn that SMS-based 2FA remains vulnerable to SIM-swapping and interception.
