create different ssh key according the article Mac Set-Up Git
$ ssh-keygen -t rsa -C "your_email@youremail.com"
Please refer to github ssh issues for common problems.
for example, 2 keys created at:
~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan
then, add these two keys as following
$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan
you can delete all cached keys before
$ ssh-add -D
finally, you can check your saved keys
$ ssh-add -l
$ cd ~/.ssh/
$ touch config
$ subl -a config
Then added
#activehacker account
Host github.com-activehacker
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_activehacker
#jexchan account
Host github.com-jexchan
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_jexchan
clone your repo git clone git@github.com:activehacker/gfs.git gfs_jexchan
cd gfs_jexchan and modify git config
$ git config user.name "jexchan"
$ git config user.email "jexchan@gmail.com"
$ git config user.name "activehacker"
$ git config user.email "jexlab@gmail.com"
or you can have global git config $ git config --global user.name "jexchan" $ git config --global user.email "jexchan@gmail.com"
then use normal flow to push your code
$ git add .
$ git commit -m "your comments"
$ git push

Excellent write-ups! This and the linked article are both great to read through. I am new to SSH and GPG in GitHub so I needed to spend a lot of time to get up to speed.
FYI I recently got a new personal Macbook, so I found I've needed this sort of setup for
git
since I use one account for work, and another for personal stuff.In case it's useful to others, I've gathered all the useful steps in the main steps, into a Bash/shell script. Helps for automation purposes, so e.g. less manual work, and also less things to remember.
Please do check it out and let me know (link below). I welcome any PRs or updates to script if needed. I tested this extensively on a Mac environment.

Updates:
~/.dotfiles
folder and adding all project.gitconfig
there, so I've updated the script to do that.After running the script, file/directory structure in user home

would now look as follows:
