How to log in using Python on a site with authorization through VK?

Question

Python

Good afternoon. I can not log in to mrandom.com (not advertising)
By pressing the "Login" button, mrandom.com/auth/vk opens (or mrandom.com/auth/vk/callback , I did not figure it out.)

After entering the data, the form is sent and in Network can see it.
Request URL: https://login.vk.com/?act=login&soft=1
Request Method: POST
And this is from below:

I took this code following the example from the Toaster, after parsing, you can understand that I am not authorized on the page.

import requests

s = requests.Session()
data = {"email":"[email protected]", "pass":"YYYYYYYYY"}
url = "http://mrandom.com/auth/vk"
r = s.post(url, data=data)

s.cookies

response = requests.get('http://mrandom.com/contests/my')
print('Result')
print(response.content)

Please help, I can't find the answer
