How to manage credentials for interactions with github.com.

Dual Work-Personal SSH Accounts

Nothing changes for your personal account (assuming it already exists)

For your work account:

  1. Create an ssh key and save it to a named file

# This creates ~/.ssh/work_rsa and ~/.ssh/work_rsa.pub
$ ssh-keygen -t rsa -C "bob-work@gmail.com" -f "work"

  1. Upload the ssh key to your github work account

  2. Create a new github.com configuration in ~/.ssh/config

Host work
    Hostname github.com
    User git
    IdentityFile ~/.ssh/work

  1. Test the ssh key

$ ssh -T git@github.com
Hi bob! You've successfully authenticated, but GitHub does not provide shell access.
$ ssh -T git@work
Hi bob-work! You've successfully authenticated, but GitHub does not provide shell access.

  1. Clone

$ git clone git@github.com:bob/my_open_source_repo.git
$ git clone git@work:mercury/thirteenth-floor.git
