Hello everyone! I'm Ashish Maurya, a full-time software developer and part-time freelancer. With the different projects I work on for different clients, I often have to set up work emails with Git. Unfortunately, it can be tricky to set up multiple Git accounts on the same machine. In this article, I'll show you how to use multiple Git accounts on the same machine using SSH keys.
Well setting up one git account is easy setting up multiple accounts is not so much especially when you have to keep switching between the different git accounts. (As I mentioned part-time freelance developer)
There is a way to set up multiple accounts in Git on the same machine using ssh keys. This article will show how to set up numerous git accounts on the same Machine.
SSH keys.$ ssh-keygen -t ed25519 -C "your_email@example.com"
.ssh keys, don't name it the same or else it will be overwritten.
For this article, I will use test it as a dummy username but you can name it anything you like. In case you want to check for existing keys follow this Link.
With SSH keys, if someone gains access to your computer, the attacker can gain access to every system that uses that key. To add an extra layer of security, you can add a passphrase to your SSH key. To avoid entering the passphrase every time you connect, you can securely save your passphrase in the SSH agent.
SSH key$ eval "$(ssh-agent -s)"
>> Agent pid 375
$ ssh-add ~/.ssh/test
Identity added: /c/Users/Lenovo/.ssh/test (your_email@example.com)
SSH key to GitHubCopy the above SSH public key to your clipboard.
$ clip < ~/.ssh/test.pub
# Copies the contents of the test.pub file to your clipboard
Open the setting in your GitHub account.
Click on add New Key and a prompt will open in that text area paste the keys and Add them.
Once that is added you have added the key Successfully.
Now repeat the same process for your work account or personal account. And once done.
Edit/Create ssh config file (~/.ssh/config):
# Default github account: personal
Host github.com
HostName github.com
IdentityFile ~/.ssh/personal # your personal SSH key
IdentitiesOnly yes
# Other github account: test
Host github-test
HostName github.com
IdentityFile ~/.ssh/test #Your test/ Organization key
IdentitiesOnly yes
Adding SSH private key to your agent.
$ ssh-add ~/.ssh/personal
$ ssh-add ~/.ssh/test
Test the connection.
$ ssh -T git@github.com
$ ssh -T git@github-test
you will get the following prompt with each command, you might see this kind of warning type yes in each case.
The authenticity of host 'github.com (192.30.252.1)' can't be established.
RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:
Are you sure you want to continue connecting (yes/no)?
If everything is OK, you will see these messages:
Hi personal! You've successfully authenticated, but GitHub does not provide shell access.
Hi test! You've successfully authenticated, but GitHub does not provide shell access.
Now all are set, just clone your repositories
$ git clone git@github-test:org2/project2.git /path/to/project2
$ cd /path/to/project2
$ git config user.email "test@org2.com"
$ git config user.name "Test"
In conclusion, setting up multiple Git accounts on the same machine can be tricky, but it is possible with the use of SSH keys. By following the steps outlined in this article, you can easily manage multiple Git accounts from the same machine. With SSH keys, you can securely access multiple accounts without having to constantly enter and store passwords.
