Configuring Git to use Multiple Accounts (Win)

If you use multiple accounts with Git (for instance, a work or personal GitHub account in addition to your GA GitHub Enterprise account), you need to configure git a bit differently than the default instructions outlined on github.com. Use this page as your guide for finishing your GitHub Enterprise setup.

• Log into your account at https://git.generalassemb.ly
• Follow these steps to create a new SSH Key (a special, very secure, key which allows your laptop access to your github account without having to remember your github password).

Generating a new SSH key

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

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

   This creates a new ssh key, using the provided email as a label.

3. When you're prompted to "Enter a file in which to save the key," type

   /c/Users/[username]/.ssh/id_rsa_ga

   where [username] is your Windows username, and then press Enter.

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

Adding your SSH key to the ssh-agent

1. If you're NOT using Git Bash, paste the text below to start the ssh-agent in the background.

   eval "$(ssh-agent -s)"

   The output should be Agent pid followed by some numbers.

2. In your editor, navigate to the c:\Program Files\Git\etc\ssh\ folder, then open the file named ssh_config (if this file doesn't exist, go to the terminal, run touch c:\Program Files\Git\etc\ssh\ssh_config, then open the file in your editor.)
3. Add a second entry to your file using the following as a template:

   
       # my GitHub account 
       Host personal
         HostName github.com
         User git
         AddKeysToAgent yes
         UseKeychain yes
         IdentityFile ~/.ssh/id_rsa
         IdentitiesOnly yes
       
       # GA github Enterprise
       Host GA   
         HostName git.generalassemb.ly
         User git
         AddKeysToAgent yes
         UseKeychain yes
         IdentityFile ~/.ssh/id_rsa_ga
         IdentitiesOnly yes
       
       # wildcard
       Host *
         AddKeysToAgent yes
         UseKeychain yes
     

4. Save your changes
5. Paste the text below to add your SSH private key to the ssh-agent and store your passphrase in the keychain. (If you used a name other than id_rsa_ga in the steps above, be sure to use that name here as well.)

   ssh-add ~/.ssh/id_rsa_ga

6. Add your new SSH Key to GitHub Enterprise following these instructions
7. Verify your key works by running the following:

   ssh -T git@git.generalassemb.ly

   You should see output similar to:

   Hi <you>! You've successfully authenticated, but GitHub does not provide shell access. Connection to git.generalassemb.ly closed.
