Check if your passwords have been filtered on the Internet
The operation of this website is simple, since it is presented in search engine mode. The first thing you have to do is enter the web page, where you will immediately see a text box. In it you have to write the email you want to check, and the page will tell you if there is any account linked to it that has been exposed.

If when you write an email the screen below the green screen means that your email has not appeared in any of the massive leaks that the web has collected, and therefore you are not immediately exposed to having your account stolen.
But if what appears is the color red you will be in trouble because your password has been filtered. Then, the page will tell you how many massive leaks your email appears, and just below you will see a list of all the pages in which your registration data have been exposed. Therefore, you only have to go to each site in the list and change the password.
