For the initial "Have I Been Pwned" lookup, a summary of the types of results would help users better understand the associated risk.

So this:

"Oh no, pwned in 20 breaches"

... could be expanded to something like:

"Oh no, pwned in 20 breaches:

• 7/20 leaks included password or password hashes

• 13/20 do NOT have passwords - just contact and similar metadata"

... etc

This could be styled nicely however it makes sense - in a table, pie chart, etc. And it could be expanded later to include whatever level of detail makes sense - maybe strong/slow hashes vs weak/fast hashes, etc.

The broad idea is to contextualize the results quickly so that users can broadly categorize their risk.
