I don't have ~/.ssh/config file but multiple GitHub accounts works, how?

Question

I'm trying to configure another GitHub account to be able work from my machine. I started to looking around and I found:

Set up multiple ssh profiles by creating/modifying ~/.ssh/config. Note the slightly differing 'Host' values:

So as I (already) have multiple accounts working (I don't remember how and when I did that) I wanted to just add another entry in ~/.ssh/config. But it appears that I don't have such file. Maybe it is located somewhere else? Or maybe my machine is configured in some other way? Where to start searching?

I wanted to just add another entry in ~/.ssh/config

You can create it, but:

• you need to have generate public/private keys with a different name

  ssh-keygen -q -P "" -t rsa -f ~/.ssh/key2
  

• you need to have registered ~/.ssh/key2.pub on your remote server second account

• you need to have a config file with:

  Host github2
  HostName github.com
  User git
  IdentityFile /home/me/.ssh/key2
  

Note the User here: 'git', not 'another GitHub account'

• you need to change the origin remote URL to use that entry:

  git remote set-url origin github2:MySecondAccount/MyRepo.git
