I can see that GitHub allows you to have multiple mail account and associate every organization you are part of with a different address.
Can this be done also for SSH keys?
What I would like to do is having two different keys, one to push on my private repository, another to push on an organization repository.

On Github, you can add several ssh keys to your account, simply go to your profile/ssh and click “Add SSH key”.
But as far as I know the permissions for a repository is associated to the account, not the key. So if you are trying to limit the damage done by someone stealing your key, I believe you will need to create two accounts.

Things have changed quite a bit since this answer. There is now a path to do exactly what OP is requesting via fine grained Personal Access Tokens. The fine grained permission ability is (currently) in beta, but allows you to generate a token with least privilege, and tie it to a specific repository.
You can then use GitHub HTTP authentication (instead of SSH) to be able to push commits.
- Generate a personal access token in GitHub user settings (
Settings → Developer settings → Personal access tokens → Fine Grained Tokens (beta) → Generate new token*)
- Be sure to grant Read / Write to
Code and Commit Statuses
- Add this token to your
.git/configlike so:
[remote "origin"]
url = https://username:[email protected]/username/repo.git
