Generating a new SSH key and adding it to the ssh-agent

After you’ve checked for existing SSH keys, you can generate a new SSH key to use for authentication, then add it to the ssh-agent.

Generating a new SSH key

1. Open TerminalTerminalGit Bash.
2. Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
   # Creates a new ssh key, using the provided email as a label
   Generating public/private rsa key pair.
   

3. When you’re prompted to “Enter a file in which to save the key,” press Enter. This accepts the default file location.

   Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]
   

4. At the prompt, type a secure passphrase. For more information, see “Working with SSH key passphrases”.

   Enter passphrase (empty for no passphrase): [Type a passphrase]
   Enter same passphrase again: [Type passphrase again]
   

Adding your SSH key to the ssh-agent

Before adding a new SSH key to the ssh-agent, you should have checked for existing SSH keys and generated a new SSH key.

1. Ensure ssh-agent is enabled:

   # start the ssh-agent in the background
   eval "$(ssh-agent -s)"
   Agent pid 59566
   

2. Add your SSH key to the ssh-agent. If you used an existing SSH key rather than generating a new SSH key, you’ll need to replace id_rsa in the command with the name of your existing private key file.

   $ ssh-add ~/.ssh/id_rsa
   

3. Add the SSH key to your GitHub account.
