What are SuperTokens and Stack Auth?
SuperTokens is an authentication framework that handles user login, registration, and session management for your applications. It provides ready-made solutions for email password login, social login through providers like Google and Facebook, passwordless authentication using magic links or one-time codes, and more.
The tool uses a unique design where your backend sits between your frontend and SuperTokens. This gives you more control to customize the authentication process while keeping it secure. SuperTokens manages the complex security tasks automatically, including protecting against common attacks and handling session tokens.
You can choose to run SuperTokens on your own servers completely free, or use their managed cloud service that handles all the technical work for you.
Stack Auth is a complete authentication solution that handles all the complex parts of user login and management. When you add it to your application, you get ready-made login pages, account settings, password reset flows, and user dashboards without writing code for these features yourself.
The platform supports multiple ways for users to sign in, including regular passwords, social logins through Google or GitHub, magic email links, and modern passkeys using fingerprints or face recognition. It also handles advanced features like two-factor authentication for extra security, team management for business apps, and permission systems to control what different users can do.
Stack Auth is fully open-source and licensed under MIT and AGPL, meaning you can see exactly how it works and modify it if needed.
