SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill streamlines the implementation of modern, secure, and user-friendly authentication methods, moving beyond traditional passwords to enhance security and user experience.

Core Features & Use Cases

  • Passwordless Authentication: Implement passkeys (WebAuthn), magic links, and social logins (Google, Apple).
  • Multi-Factor Authentication (MFA): Integrate passkeys and other methods as robust second factors.
  • Use Case: Set up a new web application to allow users to sign up and log in using their device's biometrics (passkeys) or a quick Google sign-in, ensuring a smooth and secure onboarding process.

Quick Start

Implement passkey registration for a new user in a Next.js application.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement passkeys and WebAuthn for passwordless authentication in a Next.js app?▼

Implementing passkeys in Next.js requires frontend libraries like @simplewebauthn/browser to handle WebAuthn registration, paired with backend Supabase Auth integration to securely manage credentials and user sessions.

What's the best way to set up OAuth social login with Google and Apple using Supabase?▼

Setting up OAuth social login involves configuring Google and Apple provider credentials in Supabase Auth, then handling the OAuth token exchange flow on your backend to establish secure user sessions without passwords.

Does this passwordless authentication approach support multi-factor authentication (MFA) configurations?▼

Yes, this approach supports MFA configurations by allowing passkeys and other passwordless methods to act as robust second factors for secure Supabase Auth session management.

Can I use magic links for user onboarding instead of traditional passwords in Supabase?▼

Yes, you can use magic links for passwordless user onboarding by sending secure, time-sensitive authentication links via email through Supabase Auth to verify users without requiring a password.

What frontend and backend dependencies do I need to configure WebAuthn credential management?▼

Configuring WebAuthn credential management requires the @simplewebauthn/browser frontend library for capturing biometric device inputs, alongside backend Supabase integration for secure credential storage and session handling.
