Company

PasswordRadar (formerly knownPass) is run by KnownPass s.r.o., Czech Republic. Its registration number and registered office will be listed here once its entry in the commercial register is public.

The product was renamed; the company and its domain were not. That is why the API host, api.knownpass.com, and the salt still carry the original name. The salt is part of every hash in the dataset, so it stays exactly as it is, and existing integrations keep working unchanged.
