Apparently not

I came across this amusing old post which contained the following quote:

OK, if you look five years down the road you can see that Passport is going to own a large chunk of the world’s Web sites. Already if you go to http://msdn.microsoft.com you’ll need Passport to download software and do other things.

Now, imagine a world where every Web site is like that.

It is pretty hard to imagine now, nine years later, because I have no idea what “Passport” was.
