Access Multiple Github Accounts From One Computer

Step 1: Step 1: Generate SSH and Add it to ssh-agent

Note: if you have two github accounts, you need to generate two SSH Key

Step 2: Configure ~/.ssh/config

Note: In order to access the different account, you must use the hostname specified inside the ~/.ssh/config file. Here is my example:

$ cat .ssh/config
Host *
ServerAliveInterval 240

# garyliu1119 account
Host github1119.com
  HostName github.com
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_ed25519
  IdentitiesOnly yes

# garyliu19 account
Host github19.com
  HostName github.com
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_rsa
  IdentitiesOnly yes

When I clone the github repo, I use the following command:

git clone -b develop git@github19.com:garyliu19/FN-External-API.git

Note: the domain name is: github19.com, instead of github.com
