What is an SSH key?

An SSH key is a secure access credential.

Principle:

Communicate securely with Github/Gitlab without entering the username/password.

How do I get and set my SSH key?

Check if you already have an SSH key:

$ ls -al ~/.ssh

If there are 2 files named id_rsa, you have an SSH key.

If you don’t have yet an SSH key, you have to generate one:

$ ssh-keygen -t rsa -b 4096

If you set a password to your key (recommended), add it to the ssh-agent:

$ eval "$(ssh-agent -s)"
$ ssh-add -K ~/.ssh/id_rsa

Then, add the SSH key to Github/Gitlab.
