On Monday the 27th October, we will be merging in a pull request which adds an additional layer security to LibreNMS installations. This feature will be available in 25.11.0 due mid November.
When adding a new user or changing your password, we now check the chosen password hasn’t been included in a data leak using the https://haveibeenpwned.com service. You can read about how this works on their website: Have I Been Pwned: API Documentation
Please note this DOES NOT submit your passwords to a 3rd party.
However, if you do not want to use this service then you can disable it with the new setting of password.uncompromised either via the WebUI or via lnms config:set password.uncompromised false.
