| However, if you do this, you have recreated the original problem you were trying to solve! You have just replaced typing an account password with typing a key passphrase every time you wish to authenticate. There is a solution though, that will make everyone happy, using programs called ssh-agent and keychain. Using them is the subject of the next section. | However, if you do this, you have recreated the original problem you were trying to solve!

| ssh-agent is a program that runs in the background and keeps a decrypted copy of your private key in memory. Thus, you reduce the number of times you need to type in your passphrase from once per authentication event, to once every time the machine gets rebooted. | ssh-agent is a program that runs in the background and keeps a decrypted copy of your private key in memory.
