Features
Not just a yes/no answer — a full picture of what's out there and what to do about it.
Searched against a database of 1,000+ known breaches and 17.6 billion compromised records, updated as new incidents are confirmed.
Every breach is rated 1–10 based on the most sensitive data exposed, so you instantly know what deserves your attention first.
See exactly when each breach happened and spot the years you were most exposed, at a glance.
Passwords are hashed on your device and checked with k-anonymity — the full password never leaves your browser.
No raw data dumps. Every result comes with clear, prioritised next steps in language anyone can act on.
The email you check is never stored or logged — it's used once to query the breach database, then discarded.
Testimonials
A few words from early users.
"Found out one of my old accounts had been breached years ago and I had no idea. The severity score made it obvious which password to change first."
"I recommend this to everyone on my team now. The plain-language explanations mean people actually understand what to do, instead of ignoring another security alert."
"The k-anonymity password check sold me — I could finally check my passwords without that uneasy feeling of typing them into some random website."
How it works
We check it against the HaveIBeenPwned database — the same source trusted by Firefox Monitor and 1Password.
Every breach explained: what was exposed, how serious it is, and a 1–10 severity score you can read at a glance.
Clear, prioritised guidance — change this password first, watch for that scam — instead of a raw list.
