Maintaining Access to Two GitHub accounts
I have 2 different GitHub accounts and I need to maintain write access to both from may macOS laptop. Here what I did:
- Generate a two SSH keys, one per GitHub account
GitHub does not access the same SSH key for more than one account.

ssh-keygen -t ed25519 -C "gustavoserrano86@gmail.com" -f ~/.ssh/id_ed25519_github_gustavos86
ssh-keygen -t ed25519 -C "h.serranog@uniandes.edu.co" -f ~/.ssh/id_ed25519_github_hserranog
- Add each
.pub
key to the corresponding GitHub account
Go to GitHub → Settings → SSH and GPG keys → New SSH key
- Configure
~/.ssh/config
to differentiate them

# gustavos86 account
Host github.com-gustavos86
HostName github.com
User git
IdentityFile ~/.ssh/id_ed25519_github_gustavos86
IdentitiesOnly yes
# hserranog account
Host github.com-hserranog
HostName github.com
User git
IdentityFile ~/.ssh/id_ed25519_github_hserranog
IdentitiesOnly yes
- Update repo remotes to use the correct host

git remote set-url origin git@github.com-gustavos86:gustavos86/gustavos86.github.io.git
Make sure to update some-repo.git
with the corresponding repo name
1
git remote set-url origin git@github.com-hserranog:hserranog/some-repo.git
- Use
git remote -v
to verify. Example:

origin git@github.com-hserranog:hserranog/miso-readings.git (push)
