Pwned

Pwned uses the Have I Been Pwned? database created by security researcher Troy Hunt. When sites are hacked, any public information about the s and s included in that breach are added to this database. It can include names, email addresses, s, and more.

You can use Pwned to check if your or have been a part of a data breach. If so, change your s for the relevant s and do not reuse that .
