This is such a nothing burger, they’re using those first five to get partial matches then doing the actual checks locally on the hash…

`To be transparent: this check isn’t new, it has been part of the Supervisor for years. It checks app options that are marked as passwords. A recent release fixed the warning that surfaces it, which is why you’re seeing it now.

Privacy was a design requirement for this feature from the start, which is why your secrets never leave your system. The Supervisor hashes them locally and sends only the first 5 characters of the SHA-1 hash to Have I Been Pwned. HIBP returns every hash starting with that prefix, and the matching happens on your own instance. You can see exactly what it does here: github.com/home-assistant/supervisor/…/pwned.py

You are right that our documentation should have explained this, including how to turn it off. We’ll get that page updated.
