Just checked, I am fully logged in in a clean ddg browser session, and can accept friend requests, etc. But I don't have 2fa enabled.

It may be that the link only worked once. Try again after logging out. Does it work?

Clicked it again, it says: The link you clicked may have stopped working or the page has been moved.

Can still log in as often as I want into clean browser sessions. Even when I log out, clean the session, tapping the url logs me in again.

And every time FB sends me an email: "Someone logged in from some location, was it you?"
