There are times you SSH into a server frequently enough to not want to always enter a password. Here's how to avoid the password prompt.

1. Create your SSH key

ssh-keygen

Note: Just hit enter for each of the prompts. If you actually enter a passphrase, you'll still have to type the it every time.

2. Copy your key to the remote server

cat ~/.ssh/id_rsa.pub | ssh USERNAME@DOMAIN.TLD "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

That's it! On your next SSH login you won't be prompted for a password.
