How to get the id of an authorized VK user?

Question

Marketing

Searched, found not quite right.
Basically it tells how to subscribe discreetly, etc. In short, not all that is necessary and that is not entirely legal.
I know that many sites take out id if it is authorized and even if not.
Thanks for the replies or any thoughts.
I don't want to take a widget, make it invisible and attach it to the cursor.
Although thoughts if how to pull out all the information, but I want to keep privacy.
And then let the user decide.
By the way, I found a way to steal not only private data, but the page as a whole.
What to do? In support they wrote what they usually write, everything is fine.

Answer 1

why, make a request to VK api users.get where the id is taken from the current authorized user, and you will be happy, the token is not needed. open method
