Git setup for different accounts pointing to different repos

I recently had an issue that looked like this:

• I have a personal project on github.com in which I author commits with my personal GitHub account.
• I have a company project on github.com in which I author with my company account.

I had two separate SSH keys for this, one personal and one company, however, since both projects lived in github.com, doing git pull or git push would not know which SSH key to use.

The solution (for macOS): a ~/.ssh/config file where a new DNS name is created to separate the work vs personal case:

Host github.com-company
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_algorithm_company

Host github.com-personal
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_algorithm_personal

No that i create two aliases here, github.com-company and github.com-personal.

Then, set the correct remote url for each project.

For the company project:

git remote set-url origin [e-mail]-company:CompanyName/company-project

And for the personal project:

git remote set-url origin [e-mail]-personal:domantasjurkus/personal-project
