Multiple accounts for Github

Github doesn’t allow you to use the same SSH key for multiple accounts, because in this case server wouldn’t detect by your key which account you want to use. Fortunately, Github makes correct redirects from subdomains. Let’s use it.

Add new ssh key:

ssh-keygen -t rsa -C "newuser@yourteam.com" -f .ssh/id_rsa_newuser
ssh-add ~/.ssh/id_rsa_newuser

Create ~/.ssh/config with following rule to say ssh use new key for new domain:

Host github.com-newuser
  	HostName yourteam.github.com
  	User git
  	IdentityFile ~/.ssh/id_rsa_ewuser

Add this line in your /etc/hosts:

192.30.253.113  yourteam.github.com

That’s all! Now use yourteam.github.com instead of github.com in your remote URL.
