By default everytime I push to github, I have a prompt asking for password.

(xgboost) guillaume@LL11LPC0PQARQ:~/git/guillaume_blog$ git push
Username for 'https://github.com': castorfou
Password for 'https://castorfou@github.com': 
Everything up-to-date

Would be great if I could leverage ssh keys to authenticate.

Update remote from https to ssh

From https://stackoverflow.com/questions/14762034/push-to-github-without-a-password-using-ssh-key,

For example, a GitHub project like Git will have an HTTPS URL:

https://github.com/<Username>/<Project>.git
And the SSH one:

git@github.com:<Username>/<Project>.git
You can do:

git remote set-url origin git@github.com:<Username>/<Project>.git
to change the URL.

In my case I have

(xgboost) guillaume@LL11LPC0PQARQ:~/git/guillaume_blog$ git remote -v
origin  https://github.com/castorfou/guillaume_blog.git (fetch)
origin  https://github.com/castorfou/guillaume_blog.git (push)

I have just to modify:

git remote set-url origin git@github.com:castorfou/guillaume_blog.git

Results

It looks like working:

(xgboost) guillaume@LL11LPC0PQARQ:~/git/guillaume_blog$ git push
