Web scraping of statistics from wordstat.yandex. How to log in?

Question

Java

Good afternoon! The task is to get view statistics for a certain keyword from wordstat.yandex.ru. I use jsoup for this. The code is as follows
Document doc= Jsoup.connect(" https://passport.yandex.ru/passport?mode=auth&from... "+URLEncoder.encode(" https://wordstat.yandex.ru/#!/history " ,"UTF-8")+"&twoweeks=yes")
.data("passwd","passwd")
.data("login","login")
.post();
In response, I get html that does not meet expectations (part of the document)
Attention
Automatic redirection to the site
is not possible.
This means that you cannot automatically redirect your browser to this site for one of two reasons:

1. This site is someone else's and we believe it belongs to phishers . If you mistakenly mistook someone else's site for Yandex and entered your username and password there, we recommend that you change your password
   as soon as possible . If you trust this other site, you can follow the link yourself:
   
2. Perhaps our internal error has occurred.
