oidc-hosted-page-go

This skill provides a comprehensive guide for Go developers to integrate secure, passwordless authentication using the MojoAuth Hosted Login Page via the OpenID Connect (OIDC) protocol. It is designed for developers working on backend systems, web services, or APIs who need to offload complex authentication logic, such as Magic Links, Email OTP, SMS OTP, social login, and Passkeys, to a reliable third-party provider. By leveraging this skill, AI coding agents can generate the boilerplate code, environment configuration, and HTTP handlers necessary to establish a robust OIDC authorization flow within a Go project. It covers the full lifecycle of the authentication process, including token exchange, CSRF protection, and ID token verification, ensuring that user identities are validated securely before creating sessions.

• Simplifies OIDC integration for Go applications using standard libraries like github.com/coreos/go-oidc and golang.org/x/oauth2.

• Automates the generation of login initiation and callback handlers with proper state management and security practices.

• Enables passwordless login capabilities, including FIDO2/WebAuthn Passkeys, without managing complex crypto implementation.

• Provides clear instructions for environment variable configuration, including MojoAuth Domain, Client ID, and Redirect URI.

• Supports various Go web frameworks such as standard net/http, chi, and gorilla/mux, allowing for flexible architectural integration.

• Requires an active MojoAuth account and basic familiarity with Go dependency management using go mod.

• Expected output includes a functional auth package containing InitOIDC initialization, LoginHandler for redirecting to MojoAuth, and CallbackHandler for processing and verifying OIDC tokens.

• Ensure that Redirect URIs in your MojoAuth dashboard strictly match the configuration provided in your Go environment variables to prevent authorization errors.

• The implementation prioritizes security by using cryptographic random state generation for CSRF protection during the authorization code flow.

• Ideal for building scalable, cloud-native backend services that prioritize a seamless user experience through passwordless authentication methods.
