ssh-add is a command for adding SSH private keys into the SSH authentication agent for implementing single sign-on with SSH. The agent process is called ssh-agent; see that page to see how to run it.
The cool thing about ssh-agent and ssh-add is that they allow the user to use any number of servers, spread across any number of organizations, without having to type in a password every time when moving between servers. This is commonly used by system administrators to move among the machine they administer. It is also widely used in universities and research institutions for accessing computing resources. However, it has also lead to proliferation of SSH keys in enterprises, and that is something administrators should be aware of and audit should take steps to address.
