API keys are the digital keys to your kingdom. A leaked API key can give attackers access to your databases, cloud infrastructure, payment systems, and more. Here's how to share them safely.
Common API Key Mistakes
- ✗Committing API keys to Git repositories
- ✗Sharing keys in Slack or Discord channels
- ✗Storing keys in shared documentation
- ✗Emailing keys to team members
- ✗Using the same key across environments
Best Practices for API Key Security
🔐 Use Environment Variables
Never hardcode API keys in your source code. Use environment variables or a secrets manager.
🔄 Rotate Keys Regularly
Set up a schedule to rotate API keys, especially for critical systems. If a key is compromised, the window of exposure is limited.
📧 Share Keys Securely
When you need to share an API key with a teammate, use a self-destructing secret link. The key is encrypted, can only be viewed once, and leaves no trace.
⚠️ Set Minimum Permissions
Follow the principle of least privilege. Only grant API keys the minimum permissions they need to function.
Share Your Next API Key Securely
Need to share an API key with a developer on your team? Use PassLink to create an encrypted, one-time link that self-destructs after viewing.
