This is a functional joke where you can check if your password has been in a internet leak. Inspired by ismycreditcardstolen.com
The technical details are a bit complex (technical explanation), but in short it does some
magic calculations to your
password and checks the result using the haveibeenpwned.com API to find out of if your password has been found
in any leaked database. And it does it without ever transfering your revealing your password or any information about it
to either me or haveibeenpwned.
No I am not.
*Technically, assuming everything works as it is perfectly safe, but I give no guarantees.
There are a few options, my recommendation is to use a Password Manager with built in support for checking your passwords. I use 1Password, but other alternatives with same or similar functionality includes LastPass , KeyPass (with a plugin) or Google Password Manager
If you are technical and don't mind the terminal you could use a simple bash script like this https://github.com/DokterW/hibp-cli
That is fine, hopefully it is useful or funny to someone.
