What is "coral" and why does it reappear in "Stay logged in for faster purchases"?

[y8s]

I recently got a notice to change my password because of who knows what nefarious activity and did so via the website (no clicking on suspicious links in emails, also selected the box for "log out of everything"). I also enabled 2FA finally. Great. 

But I notice this section in my profile called "Stay logged in for faster purchases" and I click edit to see what's there.

There is one listing for something called "coral" and since I have no idea what coral is, I click "Log out" and "done". I return to this screen and it's back. I repeat this and it's always still there. Maybe this is a legit service (like browser login?) but it's sure as heck NOT descriptive enough if it's something legit.

What's up?

Thank you,

Matt
