Sometimes when we are working with multiple accounts on the same machine with GitHub we get errors where we are authorized to push and pull from a remote repository and are stuck with notifications like:

You are not the authorized author of this repository please create a fork from the GitHub branch.

Let's make it easy in just 5-6 simple and easy steps, follow each step one by one.

Suppose you are logged in with your primary account, and also have a client GitHub account from which you need to work with them. You don't need to signOut your primary account simply open your command palette like cmd, bash, and any editor.

  • Step 1: Generate and setup SSH Key :

    Please ensure that first you have SSH keys for both accounts, if you don't have an SSH key for the client account, first we need to generate.

    ssh-keygen -t rsa -b 4096 -C "client@example.com"

    Describe given above bash command line:

    ssh-keygen: used to generate SSH (Secure Shell) key pairs, which consist of a public key and a private key. These keys are used for secure authentication and communication between your computer and remote servers.

    -t rsa: This option specifies the type of key to be created. The commonly used asymmetric encryption algorithm in this case is RSA (Rivest-Shamir-Adleman).

    -b 4096: This option sets the number of bits within the key. A longer key gives more prominent security but may take longer to create (a 4096-bit key is very secure and is commonly used for SSH).

    -c "client@example.com": It's typically used to associate the key with an email address. In this case, you're associating the key with the email address "client@example.com."

  • Step 2: Adding SSH Key to SSH Agent:

    Firstly, we need to start the SSH agent

    eval "$(ssh-agent -s)"

    Describe given above bash command line:

    eval: command is used to evaluate the commands produced by ssh-agent -s.

    ssh-agent: responsible for managing SSH keys and facilitating secure SSH connections.

    -s: that need to be evaluated by the shell to set up the agent environment.

    After starting SSH we need to add the client key to the agent:

    ssh-add ~/.ssh/your-client-ssh-key

  • Step 3: configure ssh key to Github :

    We can use any of them like Vim, nano any other bash editor. Open the editor and create a plaintext file -

    nano ~/.ssh/config

    Describe given above bash command line:

    nano: It is a text Editor.

    ~: Symbol represents your home directory.

    .ssh/config: Path of sub-directory where key is stored.

    Host github.com-client
  HostName github.com
  User git
  IdentityFile ~/.ssh/your-client-ssh-key

  • Step 4: Configuration of Git

    Open the bash editor and run these commands for the configuration your SSH key to GitHub

    git config --global user.name "Your Client's Username"
git config --global user.email "client@example.com"
git config --global --replace-all url."git@github.com:".insteadOf "https://github.com/"

  • Step 5: Work with Repositories:

    clone or create a new Git repository, always remember to use a custom name when specifying the repository URL.

    git@github.com-client:client-username/client-repo.git

If you want to test your configuration use this command.

ssh -T git@github.com-client
