It only takes a fairly straightforward combination of ssh and git setup to implement this. For users of LINUX/UNIX, follow the instructions below.

1. Open Terminal

2. Generating the SSH keys

Step-1: Write the following command: $ ssh-keygen

• After that command it should look like this:

  

Step-2: Write your folder path as shown below image:

• In the below image, I've written youraccount for the path, in that, you can write any name as per your requirement (yourname_work).

• Now for a passphrase, we need to put it empty for now.

• Once you enter an empty passphrase the next step is Enter the same passphrase again in that we put the empty passphrase again.

• Now, go to the .ssh folder.

• Run the below command: catyouraccount.pub

• Copy the key starting with ssh-rsa

• Go to your github account in the web browser and then go to the settings tabs as shown in the figure below.

• Now go to the SSH and GPG key tab as shown below image:

• Click on the New SSH key button

• You will be able to see the below screen:

  1. name: (as per your wish)

  2. key: paste the key which we've copied from the .ssh folder

• Open the config file which is present in the .ssh folder in your preferred code editor.

• The above-mentioned steps let you generate and configure an ssh key.

• You can follow these same steps as mentioned above to generate more ssh keys and configure it accordingly to set multiple ssh keys in the very same system.

• Copy the below code and paste it into the config file. Make changes in your host, hostname, and identity file as per your requirement.

#First generated and configured account with ssh key
Host github.com-shyam_work
 HostName github.com
 IdentityFile ~/.ssh/shyam-work


 #Further generated and configured account with ssh key
 Host github.com-shyam_personal
  HostName github.com
  IdentityFile ~/.ssh/shyam-personal

3. Clone Repo

git clone git@github.com-shyam_work:git-account-name/git-ssh-testing.git

git clone git@github.com-shyam_personal:git-account-name/git-ssh-testing.git

Happy Coding...
