If there is no leak found publically, the tool asks for credentials (passwords) to perform a login attempt (registration check) for different well-known websites, this could be particularly useful for Red team engagements where credentials have been found elsewhere. If credentials are used somewhere else, they are displayed in the results as shown in the following screenshot.
