Guest tool
Breach Monitor
See if an email has appeared in known data breaches. We send the address to Have I Been Pwned only to run this check, and we do not store it. Guest-friendly, and password-free for the email check.
Temporarily paused
Breach check is back this weekend
Get the free checklist meanwhile. We are finishing the Have I Been Pwned connection, so the email check is paused until this weekend. We are not asking for an email or consent until it is ready. The check will never ask for a password, and we will not store the address.
Want to check a password instead? That tool runs in your browser and never sends the password to us. Open the password check →
This service uses the Have I Been Pwned API. Results are a snapshot of known public incidents, not a full security audit.
