Have I Been Pwned (pwned passwords)
An index of accounts and credentials that have appeared in known data breaches. The Pwned-Passwords range endpoint is keyless, so our search can query it directly, while the fuller breach-lookup API is paid and individual account checks happen on the website itself. Use it to confirm whether a credential has surfaced in a leak. The service is flagged as degraded in our latest checks, so the website may be inconsistent to reach.
