This question already has an answer here:
I got an email from at least one site saying they use Cloudflare and due to the recently discovered leak they're recommending I change my password on their site.
But I don't have a password on their site, I use the "Log in with Facebook" option.
Do I need to reset my Facebook password, or take any other action on Facebook to ensure that leaked data cannot be used to access any of my accounts? If I need to take some other action, what is it and how do I do it?
