If you use GitHub, it is always better to setup ssh key as it it will save you all the time that you will spend entering your email address and password into the console every time you push a commit could have been spent coding.

In this tutorial, we’ll take you through the steps to configure ssh key on github:

1. Check for an existing ssh key pair

If you already have an existing ssh key pair, no need to create a new one.

Create a new ssh key pair if you do not have one :

ssh-keygen 

Now, view the contents of the file that was created.

cat ~/.ssh/id_rsa.pub

Copy the contents of id_rsa.pub. Now, go to your github account > Settings > SSH and GPG keys > Add SSH keys
Paste the content of id_rsa.pub you copied there.

2. Test the Authentication

 ssh -T [email protected]

On successful login , you’ll see

Hi username! You've successfully authenticated, but GitHub does not provide shell access.

Now run the following command:

git remote set-url origin [email protected]:username/your-repository.git

Edit the README.md file in your repo & the add & commit the changes:

git add -A
git commit -am "Update README.md"
git push

Now, On executing “git push” command, it should not prompt for username & password.
