How to get the name of an authorized VK user on your site?

Question

JavaScript

I'm interested in the question of how you can get the username of the user who visited my site if he is authorized in VK.
Without forcing him to log in through the created application.
Thanks in advance.

Answer 1

With a special desire, you can pull out not only the name. There was an interesting article on Habré (well, maybe a couple ) related to ClickJacking . A similar question on Toaster .
But I must be careful. It is punishable. Big Brother is always on the lookout for this kind of activity. :)

Get a valid authorization token for VK.
No way.
