#This is a how to on how to have multiple GitHub accounts on one machine.

1. Create a SSH key/s.

• If ~/.ssh/ does not exist - create one
• ssh-keygen -t rsa -C "your-email-address"
• Be careful to not override your existing keys

• E.G Use something like the following ~/.ssh/id_rsa_YOUR_NEW_KEY

2. Attach the key you have just created to GitHub.

• Go to "Your profile" -> "Settings" -> "SSH and GPG keys" -> "New SSH key"
• Open your ~/.ssh/id_rsa_YOUR_NEW_KEY.pub and copy the entire string to the GitHubs key text field and save the key.

3. Start your SSH agent

• Type eval ssh-agent`` in your git bash

4. Add your SSH key

• Type ssh-add ~/.ssh/id_rsa_YOUR_NEW_KEY

5. Create SSH config

• In git bach touch ~/.ssh/config
• Open it with editor and paste:

Host github.com
 HostName github.com
 User git
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/id_rsa #Here you have to enter your default SSH key that you are going to use for github
 AddKeysToAgent yes
 # Copy the following lines as many times you like, make sure you change the key and the host if needed
 Host github-YOUR_ACCOUNT_NAME
   HostName github.com
   User git
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/id_rsa_YOUR_NEW_KEY #The key you have just created
   AddKeysToAgent yes

• Be sure to remove the comments from the above

5. To add remote or clone a repository use:

• git remote add origin git@github-YOUR_ACCOUNT_NAME:Git_Hub_Account/repository.git Be careful! [email protected]:Git_Hub_Account/repository.git is the default address given by git when you create your repository. You have to change that with the host you have provided e.g : git@github-YOUR_ACCOUNT_NAME:Git_Hub_Account/repository.git
• git clone git@github-YOUR_ACCOUNT_NAME:Git_Hub_Account/repository.git

If you don't want to be prompted everytime you try to reach the remote for a SSH passphrase you can do the following:

1. Create a .bashrc if you do not have one

• in git bash nano ~/.bashrc
• Write and save the following:

        # Set up ssh-agent
        SSH_ENV="$HOME/.ssh/environment"
        
        function start_agent {
            echo "Initializing new SSH agent..."
            touch $SSH_ENV
            chmod 600 "${SSH_ENV}"
            /usr/bin/ssh-agent | sed 's/^echo/#echo/' >> "${SSH_ENV}"
            . "${SSH_ENV}" > /dev/null
            /usr/bin/ssh-add ~/.ssh/id_rsa_YOUR_NEW_KEY
            /usr/bin/ssh-add ~/.ssh/id_rsa
        }
        # Source SSH settings, if applicable
        if [ -f "${SSH_ENV}" ]; then
            . "${SSH_ENV}" > /dev/null
            kill -0 $SSH_AGENT_PID 2>/dev/null || {
                start_agent
            }
        else
            start_agent
        fi
