Strong User Authentication

Interstellar uses hardware-backed biometrics already built into modern smartphones to provide strong, invisible authentication. Users authenticate with a fingerprint or face scan, but the actual security is enforced by a secure chip inside the device, never accessible to the app or operating system.

This method ensures that only the real device owner can authorize wallet access—without the need for passwords or PIN codes. For apps, it means fewer failed logins, no password resets, and a frictionless path to secure interaction with the blockchain.
