Add custom login, registration, user settings to your Next.js & React single page application (SPA)

Integrating authentication and user management into a Next.js React app can be efficiently achieved using Ory Kratos, an open-source identity platform, and the Next.js Edge Runtime. Ory Kratos provides a comprehensive solution for handling multi-factor authentication, social sign-ins, custom identity models, and various user flows such as registration, login, account settings, and verification. Developers can create tailored user interfaces using simple APIs, and deploy the application using platforms like Vercel. The guide outlines setting up Ory Kratos both locally and on the Ory Network, configuring UI endpoints, and rendering forms for different user flows including registration, recovery, and two-factor authentication. Additionally, it covers implementing error handling, running end-to-end tests, and deploying the app while ensuring that authentication processes are seamless and secure.
