Password Health Check
See whether your password has shown up in a known data breach, and grab a strong passphrase you can actually remember.
Check a password
Privacy: we never see your password. We send only the first 5 characters of a one-way scrambled version (a SHA-1 hash) to the breach database, then check the rest right here in your browser. This is called "k-anonymity" — it is the same method 1Password and Firefox use.
