Adding SSH key to GitHub
3 min read
Using the Github SSH protocol, you can connect to GitHub and sync with repositories without supplying your username and personal access token each time you push, pull, merge, or any Github-related command.
You can watch the video tutorial or read the text below.
Generate SSH Keys for GitHub
If you are a windows user or you face any difficulty while generating your ssh keys, you can follow this tutorial and come back to proceed further steps.
First, open your terminal and run
ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org"
Replace "email@example.com" with your email
It will ask you a few questions, keep on pressing enter till you get the output something like below.
Generating public/private rsa key pair. Enter file in which to save the key (/home/nitin/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in id_rsa Your public key has been saved in id_rsa.pub The key fingerprint is: SHA256:5asd2MT5gasdUvqhKhmKsad2qasdSfSQ/ZPgtxVbxjFhfu/U firstname.lastname@example.org The key's randomart image is: +---[RSA 4096]----+ | ..o. .+. . | | .= +o = . . | | .++. . +.. . | | ..+.o . o o . | |o...+ . D =. F | |+.oo . * o | |==+ . = | |A= . . | |*=+ | +----[SHA256]-----+
Now run the below command to print the key on the screen.
Now copy the output generated.

Adding SSH Keys to Github
Github SSH keys are added inside the
SSH and GPG keys settings
Follow the steps below to open SSH and GPG keys settings
Visit github.com and log in.
Click on the profile icon on the top right and click on settings.
Now from the left sidebar click on the SSH and GPG keys
You can also click here to open the SSH/GPG settings directly.
To add the key, click on New SSH key button at the top right, it will open up a form to fill the key.
Titlefield, enter any name to differentiate your key from the keys you will enter in the future
Keyfield paste the key you copied earlier.
Finally, click on Add SSH Key button
Setting Up Git Repository for using with SSH Protocol
If you are cloning a new repository then select the ssh tab while cloning
If you already have the repository cloned then follow the steps below:
Open your terminal, change your directory to the cloned repository, and use the below command.
git remote set-url origin
:<github username>/<repository name>
Don't forget to change
repositorynameto yours, like I have set mine below
git remote set-url origin
Now ssh keys are set up, you can try pushing them to your Github repository, you will not be asked for a username and password.
I hope, by now you should be able to add ssh keys to your Github account.
You can follow this tutorial to learn basics of Github.
