Admin account PKI authentication : howto please

Question

Hello, 
 
 In order to protect the built-in admin account, we would like to enable PKI-authentication (administration - device access). 
 Is there a document that describes how to do this please ? 
 
 Thanks,

KoenT, 
 you can generate RSA keys using any tool. For example, puttygen. 
 Have a look on google or: 
 https://support.rackspace.com/how-to/generating-rsa-keys-with-ssh-puttygen/ 
 Once the keys are generated, upload them under Administration > Device Access > Public Key authenticaiton 
 Also have a look at the Sophos online doc:
