## Task: Implement a User Authentication System

Based on your request, I've created a basic user authentication system using [PROGRAMMING_LANGUAGE]. Here's a breakdown of the implementation:

### 1. Database Schema
```sql
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL UNIQUE,
    password_hash VARCHAR(255) NOT NULL,
    email VARCHAR(100) NOT NULL UNIQUE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
```

### 2. User Registration
```python
from werkzeug.security import generate_password_hash

@app.route('/register', methods=['POST'])
def register():
    data = request.get_json()
    hashed_password = generate_password_hash(data['password'])
    new_user = User(username=data['username'], password_hash=hashed_password, email=data['email'])
    db.session.add(new_user)
    db.session.commit()
    return jsonify({'message': 'User registered successfully'}), 201
```

### 3. User Login
```python
from werkzeug.security import check_password_hash

@app.route('/login', methods=['POST'])
def login():
    data = request.get_json()
    user = User.query.filter_by(username=data['username']).first()
    if user and check_password_hash(user.password_hash, data['password']):
        return jsonify({'message': 'Login successful'}), 200
    return jsonify({'message': 'Invalid credentials'}), 401
```

### 4. Password Hashing
I've used Werkzeug's `generate_password_hash` and `check_password_hash` functions to securely hash and verify passwords. This ensures that passwords are not stored in plain text in the database.

### 5. Next Steps
- Implement email verification for new users.
- Add password reset functionality.
- Consider adding two-factor authentication for enhanced security.
