Setup multiple SSH keys for different Github account

For example: you have a repo in private organization myteamprivate with url git@github.com:myteamprivate/repo-api.git

1. Create ssh key on your machine

$ ssh-keygen -t rsa -C "your_email@youremail.com"

• Your email can be the same email with other accounts
• File name format: id_rsa_[private organization]

2. Modify ssh config

$ vi ~/.ssh/config

Then add below config

# "myteam" can be whatever, it'll be used when you clone repo
Host github.com-myteam
	HostName github.com
  AddKeysToAgent yes
	IdentityFile ~/.ssh/id_rsa_myteamprivate
  IdentitiesOnly yes
	User git

3. Copy public key and paste it in Github SSH Key

$ cat ~/.ssh/id_rsa_myteamprivate.pub | pbcopy

Then go to Github setting and paste it in Key input

Now you can clone the repo with SSH

$ git clone git@github.com-myteam:myteamprivate/repo-api.git
# "myteam" here is what you defined in ssh config Host

Note: you can change your config for repo by

$ git config user.name "Sanh Doan"
$ git config user.email "dpsanh@troodonlabs.com"

Note: If the ssh-key not auto added, you need to add ssh-agent manually

$ eval $(ssh-agent)
$ ssh-add ~/.ssh/id_rsa_myteamprivate
