OpenClaw stores every API key in one plaintext file. Every skill reads the same file. ClawHavoc proved what happens next. The fix is Auth0 Token Vault.

Auth0's platform is a  identity management solution, offering insights into authentication, authorization, and user management for web and mobile applications. Through articles, tutorials, and documentation, Auth0 offers insights into securing applications with modern identity protocols like OAuth and OpenID Connect. Developers can learn about implementing single sign-on (SSO), multi-factor authentication (MFA), and user authorization policies to enhance application security and user experience.

The ClawHavoc campaign exposed a fundamental architectural flaw in OpenClaw: all skills share a single plaintext credential file with no delegation model. Over 800 malicious skills on ClawHub exploited this to exfiltrate tokens. The real fix isn't better secret hygiene — it's applying OAuth-style delegation to AI agents. Auth0 Token Vault addresses this by issuing short-lived, scoped tokens per service through token exchange, storing credentials in the OS keyring, and restricting outbound network access per service. An open-source CLI (auth0-tv) brings this to OpenClaw directly. Fine-Grained Authorization (FGA) can further restrict what an agent can do within each service. The argument is that the same patterns that solved credential delegation for web and mobile apps must now be applied to autonomous AI agents.
