SSH login without password using OS X

KeysLately, I need to deal with more login combinations. And, most of them are about logging in to server via SSH. I decided to create a simple mechanism rather than having some login combinations written somewhere. Why not remember those logins? Well, too many things to remember.
So, I tried to create an automated system to servers and found this useful tutorial. I tried it on my Mac OS X Snow Leopard, and it works. I put it here for my reference:

  • From Terminal, run: ssh-keygen -t rsa
  • Copy/add ~/.ssh/authorized_keys:

Done!
