I received a message from haveibeenpwned.com that some of my information has been compromised.
The link in the screenshot below refers to this article.
What should I do as a response to this?
I don't remember whether or not I ever entered any information into this Apollo service (I don't even remember that I ever used it). I assume that they somehow harvested my data from other sources (e. g. social networks). I use different passwords for different web sites and I don't know which passwords were compromised. Changing all passwords is not an option (there are too many of them).
