Write authentication flow explanation

Pick your method and describe how sign-in works, and get a clear authentication section for your API docs: credentials, requests, expiry and refresh.

Context to provide

River's Authentication Flow Generator creates clear explanations of authentication mechanisms. You select auth type, and the AI writes step-by-step flow explanation developers can understand and implement. Perfect for API documentation and onboarding guides.

Unlike technical jargon, we write clear explanations. The AI understands authentication patterns and explains flows in accessible language.

This tool is perfect for backend developers documenting APIs, technical writers explaining auth, API documentation, and teams onboarding developers.

Documenting Authentication

Good authentication documentation explains the flow step-by-step, shows example requests, explains what tokens mean, and helps developers implement correctly. Clear auth docs reduce integration errors and security mistakes.

How It Works

  1. Select auth type

    Choose OAuth, JWT, API key, etc.

  2. AI writes explanation

    Generates clear flow description

  3. Add to docs

    Include in authentication section

What You Get

  • Clear step-by-step flow explanation
  • How to obtain credentials
  • How to include auth in requests
  • Token refresh procedures
  • Ready for API documentation

Common questions

Should I explain security best practices too?

Yes. Include guidance on secure storage (never commit API keys), token expiration, HTTPS requirements, and what to do if credentials are compromised. Security guidance prevents common mistakes.
