So, uh, @homeassistant@fosstodon.org has been sending partial hashes of any password it can find up to `Have I Been Pwned` for 5+ years. Only recently did they fix the display / warning to actually do something and alert on API hits. This ""feature"" is on by default, and requires console/CLI commands to disable. @homeassistant@fosstodon.org - Do better. This should be an integration like the default weather app. This should be entirely optional by users and not hidden away in the python sub-basements of the HA backrooms. disable with `ha security options --pwned=false` in a console https://github.com/home-assistant/home-assistant.io/issues/49314

Heads up, if you use home assistant, any credentials in your config have been hoovered up without your knowledge

    TL;DR:

    • No, your passwords/secrets have not been shared anywhere.
    • This is a long-standing feature and has been discussed in HA forums before.
    • You can turn it off, but that is generally not recommended.

    This post has been reported for misinformation.

    I agree due to how its phrased by OP, but its not completely off base in that HIBP is used, but it is a severe misunderstanding of how. So I’m going to leave it up for awareness, while adding some notes and a few quick links here.

    A quick quote from HA:

    Your secrets are never sent anywhere. The check uses an algorithm called K-Anonymity that makes sure the service never sees your password, not even its complete hash. Your secrets and privacy stay protected.

    The check is on by default. If you prefer not to run it, you can turn it off using the command line:

    ha security options --pwned=false

    To turn the check back on again, run:

    ha security options --pwned=true

    In short - HomeAssistant has never shared your passwords anywhere. HomeAssistant shares a part of a hash. In no way, shape, or form does this expose your passwords/secrets.

    No, your credentials have not been “hoovered up”. A hash is not reversible, and a partial hash would match far too many potential passwords to be any more accurate than random guesses.

    Still, uploading any data, especially identifying data, should absolutely not be enabled by default.

      They have been hoovered up, by home assistant. I made no claim, nor did the source, that clear-text credentials were shipped anywhere.

      This is meant to drive awareness on a transparency and dev issue, not an overt compromise. My language was maybe a bit too inflammatory though, I suppose.
