On Project → Settings, the Project Secret Key block displays the secret key that authenticates requests to the project (for APIs, tooling, or integrations that require project-level authentication—depending on your setup).
The same settings page reminds you to keep secrets safe and not share them. Anyone with the secret key may be able to act on behalf of the project within the scope allowed by your integration—store it in a secret manager or environment variables, not in source control.
If you believe a key has been compromised, follow your security process and contact Laioutr support for rotation or remediation options available for your plan.
