Security Best Practices
• Never expose secret keys in client-side applications or public repositories
• Use HTTPS only when transmitting JWT tokens
• Set appropriate expiration times - shorter is generally better for security
• Store tokens securely and implement proper token refresh mechanisms
• Validate all claims on the server side, never trust client-side validation alone
