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 protected]"

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

Modify the ssh config

$ 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 you repo and modify your Git config

clone your repo git clone [email protected]:activehacker/gfs.git gfs_jexchan

cd gfs_jexchan and modify git config

$ git config user.name "jexchan"
$ git config user.email "[email protected]" 

$ git config user.name "activehacker"
$ git config user.email "[email protected]" 

or you can have global git config $ git config --global user.name "jexchan" $ git config --global user.email "[email protected]"
