Multiple SSH Keys settings for different Git accounts

Create different SSH key pairs

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.

As an example, 2 keys are created like:

~/.ssh/id_rsa_gl
~/.ssh/id_rsa_gh

Then, add these two keys as following

$ ssh-add ~/.ssh/id_rsa_gl
$ ssh-add ~/.ssh/id_rsa_gh

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 gl
	HostName gitlab.my-corp.com
	User git
	IdentityFile ~/.ssh/id_rsa_gl

#jexchan account
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_gh

Clone you repo and modify your Git config

clone your repo git clone git@github.com:johndoe/his-repo.git john-doe_repo

cd john-doe_repo and modify git config

$ git config user.name "Mike Me"
$ git config user.email "mikeme@gmail.com" 

$ git config user.name "Mike Me"
$ git config user.email "mikeme@my-corp.com" 

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

then use normal flow to push your code

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