Pass Monitor would be WAY more useful if it actually gave more information. Just saying "xyz@xyz.com was found in this breach" does not give enough information. What was the password? Was it one that hasn't been used in 10 years? Oh, no problem. But Pass Monitor doesn't show me, so I don't know.

This is particularly needed in breaches like pastes and things which are not tied directly to one specific site or service.

I know this is possible since some other services provide this information, either the full password or at least the first few characters of the exposed password. I don't see any issue with providing this information to users who prove ownership of their monitored email addresses.
