React Native Passkey Integration

react-native-passkey provides native Passkey support for React Native applications targeting iOS 15.0+ and Android API 28+. It bridges WebAuthn API calls to the native platform credential managers, enabling secure, passwordless authentication. The package is currently at version 3.3.3 and maintains an active release cadence, with several minor and patch releases in the past year addressing fixes, updates, and new features like PRF extension support and improved error handling. A key differentiator is its direct native integration, abstracting away the platform-specific complexities of FIDO2 attestation and assertion, and offering support for advanced features like `largeBlob` and `authenticatorSelection` options. It ships with TypeScript types, facilitating safer development. The library works by taking FIDO2 attestation/assertion requests (typically from a backend) and handling the native UI and cryptographic operations, returning FIDO2 results for server verification.
