Multiple SSH Keys for Github

How to manage two Github users

If you want to have repos from two different Github users on the same machine, follow this steps:

• Generating a new SSH key
  • IMPORTANT: save your id_rsa to a different file, ex: id_rsa_second_user
• Adding the new SSH key to GitHub
• Add an alias to your ssh config editing $HOME/.ssh/config:

Host second-user-github
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_second_user

• Test both your connections with these commands:

$> ssh -T git@github.com
Hi <NORMAL_USER>! You've successfully authenticated, but GitHub does not provide shell access.

$> ssh -T git@second-user-github
Hi <SECOND_USER>! You've successfully authenticated, but GitHub does not provide shell access.

• Now you are ready to clone repos with the second user. Remember to change the repo url when you clone it:

# Normal repo url: git@github.com:USERNAME/REPO_NAME.git
# Replace to: git@second-user-github:USERNAME/REPO_NAME.git

$> git clone git@second-user-github:USERNAME/REPO_NAME.git
