🚀 Quick Start (Literally 2 Minutes)

Step 1: Minimal Setup (5 lines)

from flask import Flask
from flask_headless_auth import AuthSvc

app = Flask(__name__)

# Minimal config (sensible defaults)
app.config['SECRET_KEY'] = 'your-secret-key'
app.config['JWT_SECRET_KEY'] = 'your-jwt-secret-key'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///app.db'

# Initialize - ONE LINE!
auth = AuthSvc(app)

if __name__ == '__main__':
    app.run()

That's it! 🎉 Your API now has:

POST /api/auth/login - User login
POST /api/auth/signup - User registration
POST /api/auth/logout - Secure logout
GET /api/auth/user/@me - Get current user
POST /api/auth/token/refresh - Refresh tokens
... and 15+ more endpoints!

Step 2: Use in Your Frontend

// React, Next.js, Vue, Angular - any frontend!
const response = await fetch('http://localhost:5000/api/auth/login', {
  method: 'POST',
  credentials: 'include', // Important for cookies!
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ email, password })
});

const data = await response.json();
console.log('Logged in:', data.user);

OR use our React package for even easier integration:

npm install @headlesskits/react-headless-auth

import { AuthProvider, useAuth } from '@headlesskits/react-headless-auth';

// One-line provider
<AuthProvider config={{ apiBaseUrl: 'http://localhost:5000' }}>
  <App />
</AuthProvider>

// Use anywhere
const { user, login, logout } = useAuth();

🎯 Real-World Usage

Basic Setup (Default User Model)

from flask import Flask
from flask_headless_auth import AuthSvc

app = Flask(__name__)
app.config.from_object('config.Config')

# Uses built-in User, Role, Token models
auth = AuthSvc(app)

if __name__ == '__main__':
    app.run()

Advanced Setup (Custom User Model)

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_headless_auth import AuthSvc, UserMixin

db = SQLAlchemy()

# Your custom User model
class User(db.Model, UserMixin):
    __tablename__ = 'users'
    
    # Required fields (validated at startup)
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(255), unique=True, nullable=False, index=True)
    password_hash = db.Column(db.String(1024))
    is_verified = db.Column(db.Boolean, default=False)
    is_active = db.Column(db.Boolean, default=True)
    mfa_enabled = db.Column(db.Boolean, default=False)
    provider = db.Column(db.String(50), default='local')
    
    # Your custom fields
    first_name = db.Column(db.String(100))
    last_name = db.Column(db.String(100))
    company = db.Column(db.String(200))
    subscription_tier = db.Column(db.String(50), default='free')
    # ... any fields you want!

app = Flask(__name__)
db.init_app(app)

# Use your custom model
auth = AuthSvc(app, user_model=User)

⚙️ Configuration

Minimal Config (Secure Defaults)

# config.py
class Config:
    # Required
    SECRET_KEY = 'your-secret-key'
    JWT_SECRET_KEY = 'your-jwt-secret-key'
    SQLALCHEMY_DATABASE_URI = 'sqlite:///app.db'
    
    # That's it! Everything else has secure defaults

Production Config (All Options)

# config.py
import os

class Config:
    # Core
    SECRET_KEY = os.getenv('SECRET_KEY')
    JWT_SECRET_KEY = os.getenv('JWT_SECRET_KEY')
    SQLALCHEMY_DATABASE_URI = os.getenv('DATABASE_URL')
    
    # JWT Settings
    JWT_ACCESS_TOKEN_EXPIRES = 900  # 15 minutes (industry standard)
    JWT_REFRESH_TOKEN_EXPIRES = 2592000  # 30 days
    JWT_TOKEN_LOCATION = ['cookies', 'headers']
    
    # Cookie Security (HTTPS only in production)
    JWT_COOKIE_SECURE = True  # HTTPS only
    JWT_COOKIE_HTTPONLY = True  # XSS protection
    JWT_COOKIE_SAMESITE = 'Strict'  # CSRF protection
    
    # CORS (your frontend URLs)
    AUTHSVC_CORS_ORIGINS = [
        'http://localhost:3000',  # Local dev
        'https://yourapp.com',    # Production
    ]
    
    # OAuth (optional)
    AUTHSVC_ENABLE_OAUTH = True
    GOOGLE_CLIENT_ID = os.getenv('GOOGLE_CLIENT_ID')
    GOOGLE_CLIENT_SECRET = os.getenv('GOOGLE_CLIENT_SECRET')
    MICROSOFT_CLIENT_ID = os.getenv('MICROSOFT_CLIENT_ID')
    MICROSOFT_CLIENT_SECRET = os.getenv('MICROSOFT_CLIENT_SECRET')
    
    # Email Service (optional - for verification, password reset)
    EMAIL_SERVICE = 'gmail'  # or 'brevo'
    MAIL_SERVER = 'smtp.gmail.com'
    MAIL_PORT = 587
    MAIL_USE_TLS = True
    MAIL_USERNAME = os.getenv('MAIL_USERNAME')
    MAIL_PASSWORD = os.getenv('MAIL_PASSWORD')
    
    # Cache (optional - for performance)
    CACHE_TYPE = 'redis'
    CACHE_REDIS_URL = os.getenv('REDIS_URL')
    
    # Rate Limiting (optional)
    RATELIMIT_ENABLED = True
    RATELIMIT_STORAGE_URL = os.getenv('REDIS_URL')
    
    # Frontend redirect (for OAuth)
    POST_LOGIN_REDIRECT_URL = 'https://yourapp.com/dashboard'

📡 API Endpoints

Once initialized, your app automatically gets these endpoints:

🔐 Authentication

POST   /api/auth/signup              Register new user
POST   /api/auth/login               Login with email/password

POST   /api/auth/resend-verification Resend verification email
POST   /api/auth/request-password-reset  Request password reset
POST   /api/auth/reset-password/<token>  Reset password

🔒 MFA (Multi-Factor Auth)

POST   /api/auth/mfa/verify          Verify MFA token
POST   /api/auth/mfa/disable         Disable MFA

🔒 Protected Routes

Protect your routes with JWT authentication:

from flask import Flask, jsonify
from flask_jwt_extended import jwt_required, get_jwt_identity
from flask_headless_auth import AuthSvc

app = Flask(__name__)
auth = AuthSvc(app)

@app.route('/api/protected')
@jwt_required()
def protected():
    current_user_id = get_jwt_identity()
    return jsonify({
        'message': 'This is a protected route',
        'user_id': current_user_id
    })

@app.route('/api/admin-only')
@jwt_required()
def admin_only():
    current_user_id = get_jwt_identity()
    user = auth.user_model.query.get(current_user_id)
    
    if user.role != 'admin':
        return jsonify({'error': 'Admin only'}), 403
    
    return jsonify({'message': 'Welcome, admin!'})

🎨 Custom User Models

Method 1: Use Built-in Mixins

from flask_headless_auth import UserMixin, db

class User(db.Model, UserMixin):
    __tablename__ = 'users'
    
    # UserMixin provides: id, email, password_hash, is_verified, is_active, etc.
    
    # Add your custom fields
    first_name = db.Column(db.String(100))
    last_name = db.Column(db.String(100))
    company = db.Column(db.String(200))
    subscription = db.Column(db.String(50), default='free')
    credits = db.Column(db.Integer, default=0)

Method 2: Build From Scratch (Ensure Required Fields)

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()

class User(db.Model):
    __tablename__ = 'users'
    
    # REQUIRED FIELDS (validated at startup)
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(255), unique=True, nullable=False, index=True)
    password_hash = db.Column(db.String(1024))
    is_verified = db.Column(db.Boolean, default=False)
    is_active = db.Column(db.Boolean, default=True)
    mfa_enabled = db.Column(db.Boolean, default=False)
    provider = db.Column(db.String(50), default='local')
    
    # YOUR CUSTOM FIELDS
    # ... anything you want!

Schema Validation: We validate your User model at startup. If required fields are missing, you get a clear error:

❌ USER MODEL SCHEMA VALIDATION FAILED
Your custom User model 'User' is missing required fields:
  - mfa_enabled: Boolean, default=False
  
Add this field to your model and run migration:
  ALTER TABLE users ADD COLUMN mfa_enabled BOOLEAN NOT NULL DEFAULT FALSE;

This prevents cryptic runtime errors in production! 🎯

      - key: DATABASE_URL
        value: ${db.DATABASE_URL}
    run_command: gunicorn app:app

🔒 Security Best Practices

✅ Do This

# 1. Use environment variables
import os
app.config['SECRET_KEY'] = os.getenv('SECRET_KEY')

# 2. Enable HTTPS in production
app.config['JWT_COOKIE_SECURE'] = True

# 3. Short access token lifetime
app.config['JWT_ACCESS_TOKEN_EXPIRES'] = 900  # 15 minutes

# 4. Strong cookies
app.config['JWT_COOKIE_HTTPONLY'] = True
app.config['JWT_COOKIE_SAMESITE'] = 'Strict'

# 5. Rate limiting
app.config['RATELIMIT_ENABLED'] = True

# 6. Database backups
# Setup automated backups for your database

# 7. Monitor auth events
@auth.on_login
def log_login(user):
    logger.info(f"User {user.email} logged in from {request.remote_addr}")

❌ Don't Do This

# ❌ Hardcoded secrets
app.config['SECRET_KEY'] = 'my-secret-123'  # BAD!

# ❌ Long access tokens
app.config['JWT_ACCESS_TOKEN_EXPIRES'] = 86400  # 24 hours - TOO LONG!

# ❌ Insecure cookies
app.config['JWT_COOKIE_SECURE'] = False  # BAD in production!

# ❌ No rate limiting
app.config['RATELIMIT_ENABLED'] = False  # Easy to brute force!

Frontend Integration (React)

// AuthContext.tsx
import { createContext, useState, useContext } from 'react';

const API_URL = 'http://localhost:5000';

export const AuthContext = createContext(null);

export const AuthProvider = ({ children }) => {
  const [user, setUser] = useState(null);

  const login = async (email, password) => {
    const response = await fetch(`${API_URL}/api/auth/login`, {
      method: 'POST',
      credentials: 'include', // Important!
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ email, password })
    });
    
    if (response.ok) {
      const data = await response.json();
      setUser(data.user);
      return { success: true };
    }
    return { success: false };
  };

  const logout = async () => {
    await fetch(`${API_URL}/api/auth/logout`, {
      method: 'POST',
      credentials: 'include'
    });
    setUser(null);
  };

  return (
    <AuthContext.Provider value={{ user, login, logout }}>
      {children}
    </AuthContext.Provider>
  );
};

export const useAuth = () => useContext(AuthContext);

🤔 FAQ

How is this different from Flask-Login?

Flask-Login: Session-based, not ideal for SPAs/mobile
flask-headless-auth: JWT-based, perfect for modern apps

Can I use this with Next.js?

Yes! Perfect for Next.js. Use our React package for seamless integration:

npm install @headlesskits/react-headless-auth

Does this work with PostgreSQL/MySQL?

Yes! Just change your SQLALCHEMY_DATABASE_URI:

# PostgreSQL
SQLALCHEMY_DATABASE_URI = 'postgresql://user:pass@localhost/db'

# MySQL
SQLALCHEMY_DATABASE_URI = 'mysql://user:pass@localhost/db'

Can I use my existing User model?

Yes! Just pass it to AuthSvc:

auth = AuthSvc(app, user_model=YourUserModel)

Make sure it has the required fields (we validate at startup).

Is this production-ready?

Yes! Used in production by multiple companies. Includes:

Security headers
Rate limiting
Token blacklisting
CSRF protection
Input validation

How do I add custom endpoints?

Easy! Just add Flask routes:

auth = AuthSvc(app)

@app.route('/api/custom')
@jwt_required()
def custom():
    return {'message': 'Custom endpoint'}

📊 Performance

Token validation: <1ms with caching
Login: ~100-150ms (bcrypt hashing)
Token refresh: <10ms
Scales to: Millions of users (with PostgreSQL + Redis)

📊 Why Open Source?

Our mission: Make enterprise-grade authentication accessible to everyone, not just companies with $3,600/year budgets.

Our philosophy:

✅ Forever free - MIT licensed, no hidden costs
✅ No telemetry - Your data stays yours
✅ No paywalls - All features available to everyone
✅ Community-driven - Built by developers, for developers
✅ Production-ready - Battle-tested in real applications
✅ Security-first - Regular updates, vulnerability patches

The reality: Auth0 charges $240/mo. Clerk charges $300/mo. That's $3,600/year for basic auth. We believe authentication should be a solved problem, not a recurring expense. This is our contribution to the developer community.
