ELI5: How come some websites have massive password leaks, but large ones like Google do not?
gpt
Just to be clear for some reality into the situation.

The only times you hear about a password leak is when several things occur:

1) Passwords get stolen 2) The company actually discovers it (way harder than you'd think 3) The company thinks its in their best interest to reveal that publicly.

In all likelihood, tons of sites and passwords are hacked and stolen, including "large" sites. But they are not discovered to be hacked or the company for whatever reason does not make it public.

Be very cautious to say a site has never been hacked or stolen, they may just not know or not have said they were.
