Not sure if this is the right mag, but m/proton has very few members. lmk if i should move/delete this, thanks

I’m on proton unlimited and I turned on Dark Web Monitoring. I figure since i use bitwarden for my password manager, i need to manually sync my passwords so proton can monitor for them. what about more important stuff like adresses, DOB, SSN, etc? proton says here that they can monitor for all that stuff, but how, if they dont have it?
