GIT remote: HTTP Basic: Access denied. How to log in to a repository with git bash?

Question

git

I don't understand what nonsense. I created an ssh key in git bash and added it to my account. Created a binding to a remote repository in the local repository. When you try to push, this is nonsense. There is no information anywhere on how to log in to gitlab using gitlab. Why can't you just create variables with a password. Much easier. As I understand it, if I want to log in via ssh, then perhaps I need to write the url differently. How about via https?
In short, confusion
