Authentication

Learn about user authentication, session management, and security features in our templates.

Authentication Overview

Our templates include comprehensive authentication systems built with modern security practices. All templates support user registration, login, password reset, and session management.

Secure by Default

Password hashing, CSRF protection, and secure session handling.

Multiple Providers

Support for email/password and OAuth providers like Google, GitHub.

User Management

User profiles, roles, and permissions built-in.

Authentication Flow

Understanding how authentication works in our templates.

1. User Registration

Users can create accounts with email and password. The system validates input, hashes passwords securely, and sends verification emails.

POST /api/auth/register
{
  "email": "user@example.com",
  "password": "securepassword123",
  "name": "John Doe"
}

2. User Login

Authenticates users and creates secure sessions. Returns JWT tokens or session cookies.

POST /api/auth/login
{
  "email": "user@example.com",
  "password": "securepassword123"
}

3. Session Management

Sessions are managed securely with automatic expiration and refresh capabilities.

GET /api/auth/session
Authorization: Bearer <token>

Response:
{
  "user": { "id": 1, "email": "user@example.com" },
  "expires": "2024-12-31T23:59:59Z"
}
