Introducing Ephemeral IDs: a new tool for fraud detection

What this post added

Introduced Ephemeral IDs, a new feature that generates a unique short-lived ID for website visitors interacting with Turnstile. This ID is calculated based on aggregated client-side signals and does not rely on network-level information like IP addresses or cookies. Ephemeral IDs are designed to be short-lived and not 100% unique across different customers, making them effective for identifying patterns of fraud and abuse without compromising user privacy. They are available through the Turnstile siteverify response for enhanced fraud detection, particularly for use cases like preventing fraudulent account signups.
