+# ComfyUI Basic Auth
+
+A simple authentication middleware for ComfyUI that adds basic HTTP authentication to protect your ComfyUI instance.
+
+## Features
+
+- Basic HTTP Authentication protection for ComfyUI
+- Simple username/password configuration
+- Lightweight and easy to set up
+- Compatible with all ComfyUI versions
+
+## Installation
+
+1. Navigate to your ComfyUI custom nodes folder:
+```bash
+cd ComfyUI/custom_nodes/
+```
+
+2. Clone this repository:
+```bash
+git clone https://github.com/fofr/comfyui-basic-auth
+```
+
+## Configuration
+
+1. Create a `.env` file in the node directory:
+```bash
+COMFY_AUTH_USERNAME=your_username
+COMFY_AUTH_PASSWORD=your_password
+```
+
+2. Restart ComfyUI for the changes to take effect.
+
+## Usage
+
+The authentication will automatically be active once the node is installed and configured. When accessing ComfyUI, you will be prompted for the username and password you specified in the `.env` file.
+
+## Security Note
+
+Basic authentication sends credentials encoded (not encrypted) in the HTTP header. While this provides a basic level of protection, it's recommended to:
+
+- Use strong passwords
+- Access ComfyUI through HTTPS if exposed to the internet
+- Consider additional security measures for production environments
