PSA Nord Pass Data Breach Scanner shows previously leaked Neopets data
NordPass recently updated their data breach scanner and if you've validated your email, it will show you associated leaks and the publicly available information on that leak, which includes the 2013 leak that many people have access to.
Anyway, keep this in mind for
1. If you need to secure emails related to accounts on that leak, do that if you can.
2. If you have the email, it can be a way to get the birthday if you have NordPass.
You cannot work backwards from the username or anything and you need to confirm/validate your email for any that you want to check (otherwise it would be pretty lousy at breach protection, lol), but useful tool outside of this. Seems there was a big breach recently unrelated to Neopets.
