Multiple SSH Keys settings for different github account

create different public key

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "email@work_mail.com" -f "id_rsa_work_user1"
$ ssh-keygen -t rsa -C "email@work_mail.com" -f "id_rsa_work_user2"

Please refer to github ssh issues for common problems.

for example, 2 keys created at:

~/.ssh/id_rsa_work_user1
~/.ssh/id_rsa_work_user2

then, add these two keys as following

$ ssh-add ~/.ssh/id_rsa_work_user1
$ ssh-add ~/.ssh/id_rsa_work_user2

you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ subl -a config

Then added

#activehacker account
Host github.com-work_user1
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_work_user1

#jexchan account
Host github.com-work_user2
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_work_user2

Clone you repo and modify your Git config

clone your repo git clone git@github.com:work_user1/gfs.git gfs_work_user2

cd gfs_jexchan and modify git config

$ git config user.name "work_user2"
$ git config user.email "jexchan@gmail.com" 

$ git config user.name "work_user2"
$ git config user.email "jexlab@gmail.com" 

or you can have global git config $ git config --global user.name "work_user2" $ git config --global user.email "work_user2@gmail.com"

then use normal flow to push your code

$ git add .
$ git commit -m "your comments"
$ git push
