SimpleWebAuthn

SimpleWebAuthn is an open-source, TypeScript-first collection of libraries that simplifies WebAuthn integration for passwordless authentication, supporting modern browsers, Node.js, Deno, and other runtimes. It is designed for developers who want to add secure, FIDO2-compliant passkey or biometric login flows without the complexity of the raw WebAuthn API. Its appeal lies in reducing implementation overhead while maintaining broad platform compatibility, making strong authentication more accessible.
