BigHen simplifies and strengthens user authentication for service providers and enterprises. It uses SIM/eSIM technology on any mobile device or operating system, offering a seamless experience comparable to OTP. However, it provides enhanced security by protecting against SIM swap attacks, not storing personal data on the applet, and leveraging the robust security of SIM cards, which have never been hacked. This makes BigHen Extra both easy to use and more secure than traditional OTP methods.
