Identity Leak Checker:
On the Internet, your identity is often only your e-mail address and password. These two data, the access data, are often stolen (hacked) and then published. With an Identity Leak Checker like HPI or Have I been Pwned can you find out if your credentials are affected.

Hackers literally capture our digital identity data on a daily basis. This is often due to badly programmed software and the fact that the security of customers usually has priority B.

The stolen identity data is then sold on the Internet or Darknet or published elsewhere. These publications are also called leaks. An Identity Leak Checker is a database of stolen identity data. It informs the people concerned whether their access data is circulating somewhere and what exactly it is. There are several providers here:
