The thing is me and my brother both engaged in programming and we just learned about GitHub (and similar repository sites) but we have only one computer in the house so my question is:
Is it possible the I can have 2 (or more) ssh key for 2 (or more) GitHub accounts?
If I have 2 accounts on GitHub and I created a ssh key on both account will the ssh key of 2nd account overwrites the ssh key of the first?
$HOME/.ssh/config
Host dev
HostName dev.example.com
Port 22000
User fooey
Host github.com
IdentityFile ~/.ssh/github.key
https://www.ssh.com/ssh/config/
Otherwise use the same ssh key for both users ...
