Mobile Data Authentication is the evolution of verification methods to meet the needs of modern users. It is instant and private while providing a high level of security. Why is it more secure? Privacy awareness of users has been a growing concern as our technology continues to evolve. Unlike other mobile authentication methods like SMS OTP, biometrics (Face ID, Touch ID), header enrichment, Mobile Data Authentication protects the user by not using sensitive user data. Instead, it uses unique identifiers from the sim, the device and the verified phone number from your telecom provider.
