Pushing to Git returning Error Code 403 fatal

Question

I want to push README.md to Github.
Using Ubuntu 14.04LTS
So, I commit in the following steps.

echo "# test" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/user/repo.git
git push -u origin master

But, below error occurred.

error: The requested URL returned error: 403 Forbidden while accessing https://github.com/user/repo.git/info/refs

fatal: HTTP request failed

I know solve this error this way

git remote set-url origin https://[email protected]/user/repo.git

In this way , I must enter password.

$ git push origin master
Password: 

But I hate to enter password.

I have checked this, but I don't solved.

Please tell me how to push without password.
