# Password safety

Every password a person chooses is checked against the Have I Been Pwned breach database, k-anonymously, so only a hash prefix ever leaves the instance. It runs on account creation, changes, admin resets, basic auth and database passwords, and fails open on an instance with no outbound access.

## Also

Hashes carry their own cost, so raising it later re-hashes people in place on their next sign-in instead of locking anyone out.
