Canary Tokens
Canary Tokens are lightweight, self‑triggering alerts that act as digital tripwires. When an unauthorized party accesses or uses the token—such as a fake API key, URL, or document—the system instantly notifies the owner via email or webhook. The tool, popular among security professionals, helps detect breaches early by exposing hidden activity, and recent discussions on Hacker News highlight new integrations and community use‑cases.
