Why does Heroku require authorization?

Question

git

Good afternoon.
When trying to complete the tutorial at this stage https://devcenter.heroku.com/articles/getting-star... a question arises.
When entering the command, git push heroku masterauthorization is requested.

I'm going through the procedure heroku login, but it's still issued.
I noticed that when I enter the command heroku create, the message does not appear Git remote heroku addedas in the tutorial.
I tried to add ssh-key on the advice, but it still requires authorization:

Tell me what's the problem?

Answer 1

git usually asks for a username and password if the connection is not via ssh, but via http(s).
