Password breach check
Check whether your password has appeared in known data breaches. If it has been exposed, it is the first thing attackers try — any account using it is at risk. The check runs against the Have I Been Pwned database, and your password never leaves your browser.
A password is half the defence. The network is the other half
A strong unique password protects the account, but your traffic and real IP are still visible to your ISP and websites. A personal vpn.how server hides your traffic and gives you a clean dedicated IP — privacy at the network level, with no logs and no neighbours.

Is it safe to enter my password here?
Yes. The password is never sent anywhere: its SHA-1 hash is computed in your browser, and only the first 5 characters of the hash are sent to the breach database. They cannot be used to recover your password — that is the k-anonymity method.
What does k-anonymity mean?
The browser sends only the first 5 characters of the hash. The server returns all hashes starting with those characters (hundreds of them), and the match is found locally in your browser. The server never knows which password you checked.
Where does the breach database come from?
From the Have I Been Pwned project (Pwned Passwords) — the largest public database of passwords exposed in real data breaches (hundreds of millions of unique passwords).
What should I do if my password is found in a breach?
Change it immediately everywhere you used it, and never reuse it. Create a new unique password with our generator and enable two-factor authentication (2FA) where possible.
