Multiple SSH Keys settings for different github account

create different public key

create different ssh key:

$ ssh-keygen -t rsa -C "your_email@youremail.com"

for example, 2 keys created at:

~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan

add the public key to github account: https://github.com/settings/keys

start ssh-agent in the background eval $(ssh-agent -s)

then, add these two keys as following

$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ code ~/.ssh/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
