Why does git keep asking for username and password?

Question

git

Good day. Git problem.
Ran the following commands:

git init
git add *
git commit -m 'text'
git remote add origin https://github.com/link
git push -u origin master

I entered my username and password, everything was successfully uploaded and committed. But now every time after git push -u the console requires login and password. This was not the case before. What is the problem?

Answer 1

log in with a certificate - there will be no problems at all

Answer 2

ssh-keygen -t rsa -C "[email protected]"
#copy ssh key to github.com
subl ~/.ssh/id_rsa.pub
#test connection
ssh -T [email protected]
#set git config values
​​git config --global user.name "your name"
git config --global user.email "[email protected]"
git config --global github.user nickname
git config --global github.token your_token_here
