This guide will help you integrate our authentication solution into your application in minutes. We'll cover installation, basic configuration, and your first authentication flow.

Prerequisites

• Node.js 14+ or Python 3.8+
• npm or yarn
• An account on our platform

Step 1: Installation

npm install @authcompany/sdk
# or
yarn add @authcompany/sdk

Step 2: Initialize the SDK

import { AuthClient } from '@authcompany/sdk';

const auth = new AuthClient({
  clientId: 'YOUR_CLIENT_ID',
  domain: 'your-tenant.auth.com'
});

Step 3: Implement Login

auth.loginWithRedirect({
  redirectUri: window.location.origin + '/callback'
});

You're now ready to authenticate users! Check our detailed guides for advanced features.

Follow these security best practices to ensure your authentication implementation is secure.

Token Storage

• Never store tokens in localStorage
• Use httpOnly cookies when possible
• Implement secure token refresh flows

PKCE Implementation

Always use PKCE for public clients:

const codeVerifier = generateRandomString();
const codeChallenge = await sha256(codeVerifier);

auth.loginWithRedirect({
  code_challenge: codeChallenge,
  code_challenge_method: 'S256'
});

API Security

• Always use HTTPS
• Validate tokens on every request
• Implement rate limiting

XSS Prevention

// Sanitize user input
const sanitized = DOMPurify.sanitize(userInput);

CSRF Protection

• Use SameSite cookies
• Implement CSRF tokens
• Validate Origin headers

Regular security audits and penetration testing are recommended.

Customize the authentication UI to provide a seamless branded experience.
