Is WordPress leaking your usernames?

Many WordPress sites hand out the author list as JSON without any login. Attackers take those usernames straight into password guessing. We check read-only from outside.

How it works

Enter one domain and we read only what anyone can see on the internet to gather the risks. We send no attack requests, separate hard evidence from heuristic signals, and write “not seen” for what we could not observe.
