but you can also share or "push" your changes to other servers.
Before you can push your changes to a GitLab server
you need a secure communication channel for sharing information.
GitLab uses Public-key or asymmetric cryptography
which encrypts a communication channel by locking it with your "private key"
and allows trusted parties to unlock it with your "public key".
If someone does not have your public key they cannot access the unencrypted message.
The SSH protocol provides this security and allows you to authenticate to the
GitLab remote server without supplying your username or password each time.
