Create secure remote connections without passwords
SSH Key Authentication | How to Create SSH Key Pairs
If you need to connect to a computer remotely, one of the best and most secure methods is to use a Secure Shell (SSH) connection. This creates an encrypted connection between you and the remote host, which means that the data sent cannot be intercepted or monitored in any way.
You can also use SSH as a tunnel for other traffic, such as a secure VNC connection over SSH. One way to make your SSH connections even more secure is to use SSH keys, which replace potentially easy-to-crack passwords with a 617-digit encryption key. Here's how to generate new SSH keys on Windows, Mac, and Linux computers.
SSH keys allow you to make secure connections to remote servers or PCs without using a password using the Secure Shell protocol. SSH keys are created in pairs, with a private key and a public key that remain connected. One cannot be used without the other.
