go-webauthn/webauthn
Webauthn
This library provides a backend framework for implementing FIDO2-compliant authentication and passwordless login flows in Go applications. It serves as a server-side toolkit for managing hardware-backed identity verification, enabling developers to integrate secure, browser-based authentication protocols that utilize security keys and biometric sensors.
The project distinguishes itself by offering comprehensive tools for credential lifecycle management and hardware attestation. It handles the registration and storage of public key metadata while enforcing strict security requirements, such as origin validation and relying party identifier matching, to protect against phishing. The library also supports modular protocol extensions, allowing for the integration of custom security policies and specialized data fields during the authentication handshake.
Beyond core identity verification, the library includes primitives for processing hardware-specific metadata and digital certificates to ensure device integrity. It provides configurable settings for defining cryptographic algorithms, transport preferences, and security requirements, facilitating the implementation of multi-factor or passwordless authentication systems tailored to specific application needs.
