If you're accessing Linux servers or automating tasks between servers, rather than having to enter your user password every time, you can also use SSH public key authentication. This is a simple process that involves creating a local key and storing it within the *authorized_keys* file on the remote server.
1. Check if you already have a SSH key.
`$ ssh-add -L`
`$ ssh-add -L`
2. If you don't have one, create one.
`$ ssh-keygen`
`$ ssh-keygen`
2. Upload the key onto the server. Replace *myserver* with the hostname or IP address of your remote server.
`$ ssh-copy-id myserver`
`$ ssh-copy-id myserver`
If you're using Mac OS X and you don't have ssh-copy-id installed, download and install [Homebrew](http://mxcl.github.com/homebrew "Homebrew") and run the `brew install ssh-copy-id` command.
