Generating a new ssh-key

Open Terminal. Paste the text below, substituting in your GitHub email address.

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

This creates a new ssh key, using the provided email as a label

Generating public/private rsa key pair.

Step 1 - Create a New SSH Key

We need to generate a unique SSH key for our second GitHub account.

ssh-keygen -t rsa -C "your-email-address"

Be careful that you don't over-write your existing key for your personal account. Instead, when prompted, save the file as id_rsa_COMPANY. In my case, I've saved the file to ~/.ssh/id_rsa_work.

Step 2 - Attach the New Key
