Git - Manage Multiple Accounts

Introduction

• You can manage multiple GitHub/Gitlab accounts using the SSH configuration file and unique keys.

Steps

1. Create multiple SSH keys for each of the git accounts:

    ssh-keygen -t rsa -b 4096 -C "apurvagiri90@gmail.com" -f ~/.ssh/apurvag/id_rsa
    ssh-keygen -t rsa -b 4096 -C "sakharamshinde@gmail.com" -f ~/.ssh/sakharams/id_rsa
   

2. Update/Create the ~/.ssh/config and add the below contents:

   • Sample GitRepo’s:

    git@github.com:apurvangiri/apurvangiri.github.io.git
    git@github.com:sakharams/developerportal.git
    git@github.com:<org_name>/<repo-name>.git
   

    # Configuration for apurvangiri/apurvangiri.github.io
    Host github-apurvangiri
        HostName github.com
        User git
        IdentityFile ~/.ssh/apurvag/id_rsa
        IdentitiesOnly yes
   
    # Configuration for sakharams/developerportal
    Host github-sakharams
        HostName github.com
        User git
        IdentityFile ~/.ssh/sakharams/id_rsa
        IdentitiesOnly yes
   
    # Configuration for <org_name>/<repo_name>
    Host github-<org_name>
        HostName github.com
        User git
        IdentityFile ~/.ssh/sakharams/id_rsa
        IdentitiesOnly yes
   

3. Set the remote for the Git Repo to the respective host names:

    git remote set-url origin git@github-apurvangiri:apurvangiri/apurvangiri.github.io.git
    git remote set-url origin git@github-cloudutsuk:cloudutsukpilot/developerportal.git
   

4. Executing the git pull/push commands will use the respective keys in order to authenticate the git servers.

5. If you are using GitHub enterprise, you might have to authorize the newly added SSH key in the GitHub portal for the respective organizations in your enterprise.
