Github Multiple Accounts

Scenario

I have two github accounts, one is my personal Github account personalAccount, one is my job account workAccount. When I push code at work as workAccount to my personal repo.

it’s show - ERROR: Permission to personalAccount/repo denied to workAccount

How do I have the ability to push and pull to multiple accounts via ssh key?

Solution

Generate new SSH keys

ssh-keygen -t rsa -b 4096 -f "$HOME/.ssh/id_rsa_personalAccount"

Attach the New SSH Key
Add id_rsa_personalAccount.pub to personalAccount Github account

Add Key to the ssh-agent

ssh-add "$HOME/.ssh/id_rsa_personalAccount"
# can use ssh-add -l command to check if is successful added

Create a Config File

vim "$HOME/.ssh/config"

content of config file

# company
Host github.com
    IdentityFile ~/.ssh/id_rsa
    HostName github.com
    User workAccount
# personal
Host github.com-personal
    IdentityFile ~/.ssh/id_rsa_personalAccount
    HostName github.com
    User personalAccount

Change remote url

git remote set-url origin git@github.com-personal:personalAccount/test.git

Then I can push to my personal repo from company. Wa la la ~~
