A much better and a working solution than this is linked below.

If you have multiple Githib accounts (ex: personal and work) using SSH keys for both accounts can be pretty cumbersome. Following is a simple way to get it done with ssh config.

Prerequists

You need to follow official github guideline to create an ssh keypair, add it to your github account and complete the steps upto "Adding your SSH key to the ssh-agent" in official guide https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#adding-your-ssh-key-to-the-ssh-agent

Steps

1. Make sure you've completed creating and configuring the SSH as mentioned above.
2. Open ~/.ssh/config file in your editor. Create one if a file doesn't exist.
3. Add a host record as following

Host github.com:<YOUR_GITHUB_USERNAME>
  AddKeysToAgent yes
  IdentityFile ~/.ssh/<YOUR_SSH_KEY_FILENAME>

Replace <YOUR_GITHUB_USERNAME> with your desired github username (personal or work) Replace <YOUR_SSH_KEY_FILENAME> with your keyfile name in .ssh folder (ex: id_ed25519)

Add a host record for each of the github account you want to maintain.

Git clone

Git clone would work without any domain name changes to match your ssh condig. Just copy the ssh url and clone away. No special domain names to remember. git clone github.com:<YOUR_GITHUB_USERNAME>/your-repo.git

Please do suggest if you find any of the above needs improvement.

This did not work for me at all, while the accepted solutions work fine. You must have additional hidden configuration to make this work.
