git with ssh instead of https

If 2fa is enabled on github switch to ssh instead of https on linux

1. generate an ssh keypair on your linux box
ssh-keygen -t {rsa|dsa} 

2. add the public key to github: profile - settings - ssh keys

3. switch from https to ssh

Check your repo remote:
git remote -v
should show:
origin  https://github.com/USERNAME/REPOSITORY.git (fetch)
origin  https://github.com/USERNAME/REPOSITORY.git (push)

Change the remote:
git remote set-url origin [email protected]:USERNAME/OTHERREPOSITORY.git

verify:
git remote -v
should show:
origin  [email protected]:USERNAME/OTHERREPOSITORY.git (fetch)
origin  [email protected]:USERNAME/OTHERREPOSITORY.git (push)
