-* Securing your system
-There are a few things you can do to maximise the security of your system.
-** Use ssh keys rather than passwords
+* Improving security
+It's a lot more secure to log in to the Freedombone system using ssh keys rather than with a password. You can set that up by first running:
 
-* Improving ssh security
-To improve ssh security you can generate an ssh key pair on your system and then upload the public key to the Freedombone.

-On your local machine:
-
-#+BEGIN_SRC bash
-ssh-keygen
-#+END_SRC
-
-For extra security you may also want to add a passphrase to the ssh private key. You can show the generated public key with:
-
-#+BEGIN_SRC bash
-cat ~/.ssh/id_rsa.pub
-#+END_SRC
-
-Log into your system and open the control panel.
-
-#+BEGIN_SRC bash
-ssh username@domain -p 2222
-#+END_SRC
-
-Select /Administrator controls/ then /Manage Users/ then /Change user ssh public key/. Copy and paste the public key here, then exit.
+#+begin_src bash
+freedombone-client
+#+end_src
 
-It's a good idea to also copy the contents of *~/.ssh/id_rsa* and *~/.ssh/id_rsa.pub* to you password manager, together with the private key password if you created one.
+On your local system (i.e. whatever you're logging in to the Freedombone system from, typically a laptop). Then:
 
-There are advantages and disadvantages to using ssh keys for logins. The advantage is that this is much more secure than a memorised password, but the disadvantage is that you need to carry your ssh keys around and be able to install them on any computer of mobile device that you use. In high security or hostile infosec environments it may not be possible to carry or use USB thumb drives containing your keys and so memorised passwords may be the only available choice.
+#+begin_src
+ssh myusername@freedombone.local -p 2222
+#+end_src
 
-If you wish to only use ssh keys then log in to the Freedombone, become the root user and open the control panel with the 'control' command. Select /Security Settings/ then keep hitting enter until you reach the question about allowing password logins. Select "no" for that, then apply the settings. Any subsequent attempts to log in via a password will then be denied.
+Select *Administrator controls* and re-enter your password, then *Manage Users* and *Change user ssh public key*. Copy and paste the ssh public keys which appeared after the *freedombone-client* command was run. Then go to *Security settings* and select *Allow ssh login with passwords* followed by *no*.
 
+You'll need to make sure that you have a copy of the ~/.ssh directory on your local system. You could just copy that directory to a USB drive and then keep that somewhere safe so that you can restore the keys if you need to.
 * Administrating the system via an onion address (Tor)
 You can also access your system via the Tor system using an onion address. To find out what the onion address for ssh access is you can do the following:
