Git What is SSH?

This lesson is part of Git · All levels

Summary

SSH (Secure Shell) is an encrypted communication protocol commonly used to access servers remotely, including for Git on GitHub. SSH uses a pair of cryptographic keys: private keys that are kept secret on your computer, and public keys that are uploaded to GitHub. With SSH, authentication no longer requires a password on each push or pull.
