I have two different users at Github, one is my personal account and the other is the Uetke account. In my personal account I do sometimes play with repositories that nothing have to do with my work and therefore I like keeping things separated. However ssh keys can be used in one account at a time; fortunately the solution is easier than what I would have imaged.
First you setup your new ssh key as you probably did with the first one:
ssh-keygen -t rsa -C "email@example.com"
and remember to store it with a different name than the previous one. For example I will call each key as follows:
And add them
ssh-add ~/.ssh/id_rsa_github1 ssh-add ~/.ssh/id_rsa_github2 ssh-add -D ssh-add -l
The last two lines are just for deleting the cached files and then to list the available keys. You can verify that the proper keys were correctly installed by ssh. The last step is to modify the configuration file of ssh to enable the selection of one or the other key:
cd ~/.ssh/ touch config
Open the newly created config file with whatever editor you like and add the following:
# Github 1 account Host github.com-git1 HostName github.com User git IdentityFile ~/.ssh/id_rsa_github1 #Github 2 account Host github.com-git2 HostName github.com User git IdentityFile ~/.ssh/id_rsa_github2
The only thing you have to do now is to clone the repository using either github.com-git1 or github.com-git2:
git clone firstname.lastname@example.org:User1/repo.git
You can also add it as a remote:
git remote add email@example.com:User2/repo.git
I use this to update repositories into the Uetke profile once they are ready for the public, but in the meantime I use my personal repository for myself or extremely curious people.
