Security Best Practices

1. API Key Management

   • Store API keys in environment variables.
   • Rotate keys regularly.
   • Use different keys for each environment.

2. Access Control

   • Implement rate limiting.
   • Configure an IP whitelist.
   • Apply the principle of least privilege.

3. Monitoring

   • Enable audit logging.
   • Monitor authentication failures.
   • Set up alerts for suspicious activities.

💻 Usage Examples

Project Setup

To set up Better Auth in a new project, run:

better-auth init

Then follow the prompts to complete the configuration.

Migration Guide

To migrate authentication from an old system to Better Auth, refer to the Migration Guide in the documentation.

🛠️ Debugging

To debug, run the following command:

npm run debug

A better way to debug is to use the MCP Inspector, a tool for debugging and troubleshooting.
