Password Breach Checker API

Password Breach Checker tells you whether a password appears in the Pwned Passwords corpus of passwords exposed in data breaches. Send the password or its SHA-1 hash and get a breached flag. Paid plans add how many times it was seen and a risk level.

The Password Breach Checker API provides a simple, reliable way to integrate password breach checker functionality into your applications. Built for developers who need production-ready password breach checker capabilities without the complexity of building from scratch.
