Bazinet Vault
Privacy-first breach check

Has your password leaked?

Check a password against billions of records from real data breaches. Thanks to k-anonymity, your password never leaves your browser — we only ever see the first five characters of its hash.

Hashed on your device — only a 5-character prefix is ever sent. Nothing is stored.

A free Bazinet account is required (it keeps this service from being abused and lets us email your report). You'll be asked to sign in when you run a check.

Quick security check

Confirm you're human to keep checking passwords.
