From: http://everythingsysadmin.com/2016/03/two-github-accounts.html
Someone recently commented that with Github it is "a pain if you want to have a work and personal identity."

It is? I've had separate work and personal Github accounts for years. I thought everyone knew this trick.

When I clone a URL like git@github.com:TomOnTime/tomutils.git I simply change github to either github-home or github-work. Then I have my ~/.ssh/config file set with those two names configured to use different keys:

# TomOnTime
Host home-github.com
  HostName github.com
