I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).
Use ssh keys and define host aliases in ssh config file (each alias for an account).
-
Generate ssh key pairs for accounts and add them to GitHub accounts.
-
Edit/Create ssh config file (
~/.ssh/config
):# Default github account: oanhnn Host github.com HostName github.com IdentityFile ~/.ssh/oanhnn_private_key IdentitiesOnly yes # Other github account: superman Host github-superman HostName github.com IdentityFile ~/.ssh/superman_private_key IdentitiesOnly yes
NOTE: If you use any account frequently, you should use the default hostname (
github.com
). -
Add ssh private keys to your agent:
$ ssh-add ~/.ssh/oanhnn_private_key $ ssh-add ~/.ssh/superman_private_key
-
Test your connection
$ ssh-keyscan github.com >> ~/.ssh/known_hosts $ ssh -T git@github.com $ ssh -T git@github-superman
If everything is OK, you will see these messages:
Hi oanhnn! You've successfully authenticated, but GitHub does not provide shell access.
Hi superman! You've successfully authenticated, but GitHub does not provide shell access.
-
Now all are set, you need remeber
git@github-superman:org/project.git => user is superman git@github.com:org/project.git. => user is oanhnn
- If you need clone a repository, just do:
$ git clone git@github-superman:org1/project1.git /path/to/project1
$ cd /path/to/project1
$ git config user.email "superman@example.com"
$ git config user.name "Super Man"
- If you already have the repo set up, after the ssh config instructions, you need change the URL of
origin
, just do:
$ cd /path/to/project2
$ git remote set-url origin git@github-superman:org2/project2.git
$ git config user.email "superman@example.com"
$ git config user.name "Super Man"
- If you are creating a new repository on local:
$ cd /path/to/project3
$ git init
$ git remote add origin git@github-superman:org3/project3.git
$ git config user.email "superman@example.com"
$ git config user.name "Super Man"
$ git add .
$ git commit -m "Initial commit"
$ git push -u origin master
Done! Goodluck!
