Beyond the Single API Call: Architecting Biometric Auth in React Native

Developers often underestimate biometric authentication, assuming it's a simple API call—but orchestrating storage, prompts, and auth logic requires sophisticated architectural thinking. Understanding that biometrics work as a gate on secure storage, not a separate authentication mechanism, reshapes how you design auth flows in React Native. This architectural shift becomes critical in production scenarios involving background tasks and avoiding excessive security prompts.
