Github will be the main account and bitbucket the secondary.

Use Homebrew to install Git.

• git config --global user.name "Your Name"
• git config --global user.email "username@email.com"

Confirm changes: git config --global -l

ssh-keygen -t rsa -C "github email"

Enter passphrase when prompted. If you see an option to save the passphrase in your keychain, do it for an easier life.

Save keys to:

~/.ssh/id_rsa

Repeat for bitbucket:

ssh-keygen -t rsa -C "bitbucket email"

Save bitbucket key to ~/.ssh/id_rsa_bb

Login to remote repo and add ssh key:

pbcopy < ~/.ssh/id_rsa.pub
pbcopy < ~/.ssh/id_rsa_bb.pub

Obviously run each pbcopy command individually.

Paste into text area, under ssh settings, in your github or bitbucket account. Also give the ssh key a title like "your name" Laptop.

I am using vim, enter your editor here if different:

vim ~/.ssh/config

Create your git aliases like so:

#Github (default)
  Host gh
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa

#Bitbucket (secondary)
  Host bb
  HostName bitbucket.org
  User git
  IdentityFile ~/.ssh/id_rsa_bb

Note: On Mac OS Sierra onwards you have to add this to the top of the config file:

Host *
  UseKeychain yes
  AddKeysToAgent yes

ssh-add ~/.ssh/id_rsa
ssh-add ~/.ssh/id_rsa_bb

Enter passphrase if prompted.

Check keys were added:

ssh-add -l

ssh -T gh
ssh -T bb
