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 "your_email@youremail.com" -f account_1
$ ssh-keygen -t rsa -C "your_email@youremail.com" -f account_2

Please refer to github ssh issues for common problems.

for example, 2 keys created at:

~/.ssh/account_1
~/.ssh/account_2

first you can delete all keys before

$ ssh-add -D

then, add these two keys as following

$ ssh-add ~/.ssh/account_1
$ ssh-add ~/.ssh/account_2

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ vi config

Then added

#account_1
Host github-account-1
  HostName github.com
  User git
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/account_1
  IdentitiesOnly yes

#account_2
Host github-account-2
  HostName github.com
  User git
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/account_2
  IdentitiesOnly yes

Test SSH connect

$ ssh -T git@github-account-1
$ ssh -T git@github-account-2

Clone you repo and modify your Git config

clone your repo

git clone git@github-account-1:user1's github username/project.git project1

...or for an existing working directory

git remote set-url origin git@github-account-1:user1's github username/project.git

cd project1 and modify git config

$ git config user.name "user1"
$ git config user.email "user1@gmail.com" 

or you can have global git config

$ git config --global user.name "user1"
$ git config --global user.email "user1@gmail.com" 

then use normal flow to push your code

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