LastPass Pwned Passwords checker
This is a script for checking if any of the passwords you have stored in LastPass have been exposed through previous data breaches.
To use the script you need to have Python 3 installed and you need a CSV export of your LastPass vault. The export can be generated from the LastPass CLI with:
lpass export > lastpass.csv
or can be extracted with the browser plugin by going to the LastPass icon → More Options → Advanced → Export → LastPass CSV File (note that I did have problems getting this to work).
