Protecting your Supabase app with SuperTokens authentication.

SuperTokens is an open-source authentication solution that offers flexibility and customization for web applications, particularly when integrated with Supabase. While Supabase's own authentication, based on Netlify's GoTrue, suits apps requiring quick setup with standard email-password, social login, or phone-based OTP methods, it has limitations for high-growth or enterprise-level applications that demand more complex features like multi-factor authentication, account linking beyond shared emails, or custom user flows. SuperTokens addresses these needs by providing various sign-up methods, a pre-built UI, session management through SDKs, and customizable backend logic. It supports advanced features such as two-factor authentication, user roles, and SAML, and allows for seamless migration from other auth providers. The integration of SuperTokens with Supabase can enhance security and authorization policies using Supabase’s Row Level Security, making it a robust option for startups and organizations needing scalable and adaptable authentication solutions.
