Setting Up SSH Keys on GitHub: A Step-by-Step Guide
Introduction
Setting up SSH keys on GitHub is a crucial step in securing your online presence. SSH (Secure Shell) keys are used to authenticate and authorize access to your GitHub account, ensuring that only authorized users can access your repositories and files. In this article, we will walk you through the process of setting up SSH keys on GitHub.
Step 1: Create a New SSH Key
To start, you need to create a new SSH key on your local machine. Here’s how:
- Open your terminal or command prompt and navigate to your home directory.
- Run the following command to generate a new SSH key:
ssh-keygen -t rsaThis will prompt you to enter a passphrase for your key. Note: You can choose to use a passphrase or not. If you choose to use a passphrase, enter a strong password.
- Once you’ve entered your passphrase, the key will be generated and saved in your home directory with a
.pubfile. - You can verify the key by running the following command:
ssh-keygen -t rsa -f ~/.ssh/id_rsa.pub
Step 2: Add the SSH Key to GitHub
Now that you have your SSH key, you need to add it to GitHub. Here’s how:
- Log in to your GitHub account.
- Click on your profile picture in the top right corner and select Settings.
- Scroll down to the SSH and GPG keys section.
- Click on New SSH key.
- Enter a name for your key and click Add SSH key.
