Using multiple keys for git

Sometimes you'll have multiple github, gitlab, azure accounts and you'll have multiple ssh keys for each of those

Use ssh keys and define aliases in ssh config

• Generate ssh keypairs and add to each of your account

• Edit/Create ssh config file ($HOME/.ssh/config)

  Host github.com
       HostName github.com
       IdentityFile ~/.ssh/rsa_github
       IdentitiesOnly Yes
  Host gitlab.com
       HostName gitlab.com
       IdentityFile ~/.ssh/rsa_gitlab
       IdentitiesOnly Yes
  Host azure.com
       HostName azure.com
       IdentityFile ~/.ssh/rsa_azure
       IdentitiesOnly Yes
  

• Test the connection

  ssh -T git@github.com
  ssh -T git@gitlab.com
  ssh -T git@azure.com
