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
