• Rate Limiting: Protecting against brute-force attacks.
• Secure: Implementing security best practices, including helmet and bcrypt.
• Logging: Logging requests using Morgan.
• Error Handling: Handling errors and exceptions gracefully.
• Configuration: Using dotenv for environment variable management.
• Testing: Includes sample test cases.
• Ready for Deployment: Configured for easy deployment to platforms like Heroku or AWS.

Requirements

Make sure you have the following software installed:

• Node.js (16 or higher)
• MongoDB (or a MongoDB cloud service)
• npm or yarn (package managers)
• Git (optional)

Installation

1. Clone this repository or download the source code.

git clone https://github.com/rahulranjan937/authentication-system.git
cd authentication-system
