In order to access multiple github accounts from one computer you need to :

Step 1 - Generating SSH keys:

cd ~/.ssh
ssh-keygen -t rsa -C "[email associated with your github account #1]"
# save it as id_rsa_git_account1 when prompted
ssh-keygen -t rsa -C "[email associated with your github account #2]"
# save it as id_rsa_git_account2 when prompted

As the result of executing these commands, the following files will be generated:


Step 2 - Adding ssh keys to your github account

Using this command you can copy the key to your clipboard:

pbcopy < ~/.ssh/id_rsa_git_account1.pub

Now as the key is in your account, all you have to do is to open your github account and:

  1. Click on Account Settings
  2. Click "SSH Keys" -> "Add SSH Key"
  3. Paste your key into key field and add a relevant title
  4. Click "Add key" then enter your Github password to confirm.

Step 3 - Create a configuration file to manage the separate keys

  1. Navigate to ~/.ssh/
  2. touch config
  3. Enter the configuration to the config file:
    # githubAaccount1 
    Host account1
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_git_account1# github Account2
    Host account2
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_git_account2

Step 4 - Update Stored Identities:

ssh-add -D

Add new keys:

ssh-add id_rsa_git_account1
ssh-add id_rsa_git_account2

Test to make sure new keys are stored
ssh-add -l

Teting Push / Pull

touch readme.md
$ git ini
$ git add .
$ git commit -am "first commit"
$ git remote add origin git@account1:githubPersonal/test-personal.git
$ git push origin master
