please explain to me, like i'm 5, why so many sites have moved to single authentication using just an email?  

no passwords just the email...    

seems like a step backwards in so many ways...

yes, that is what I am referring to!nnthe issue with this method is that if your email gets compromised, now you could have many other accounts that are compromised.nnit becomes a single point of failure if no other authentication is required…
