Using SSH without a password

Suppose you have two machines, the local one (you) and the remote one (remote.com).

To ssh from the local to the server without needing a password, perform these steps:

1. ssh-keygen -t rsa
   (don’t use a passphrase. Just hit return twice)
2. scp ~/.ssh/id_rsa.pub remote.com:
3. On the remote machine (remote.com) cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
