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.

How should I store API keys securely?
Store API keys in a secrets manager like HashiCorp Vault, AWS Secrets Manager, or Azure Key Vault. Never hardcode keys in source code or commit them to Git repositories. Use environment variables as a minimum baseline.
How often should I rotate API keys?
Rotate API keys every 90 days as a baseline. For high-privilege keys, rotate every 30 days. Always rotate immediately if you suspect a key has been compromised or if an employee with access leaves the team.
What is the safest way to share an API key with a teammate?
Use a self-destructing encrypted link from a tool like PassLink. The link uses zero-knowledge encryption, auto-deletes after the recipient views it, and never stores the key in plaintext on any server.
What happens if an API key is leaked?
A leaked API key can allow attackers to access your services, exfiltrate data, rack up cloud bills, or compromise user accounts. Revoke the key immediately, rotate all related credentials, audit access logs, and investigate the blast radius.
