I couldn't figure out how to have a 2nd github identity on the one machine (none of these answers worked for me for that), but I did figure out how to be able to push to multiple different github accounts as myself.

Push as same username, but to different github accounts

1. Set up a 2nd SSH key (like so) for your 2nd github account

2. Change between accounts thus :

Push with my new 2nd github account

ssh-add -D
ssh-add ~/.ssh/ssh_key_for_my_2nd_account
git push

Push with my main account

ssh-add -D
ssh-add ~/.ssh/id_rsa   
git push
