After I have loaded public keys for administrators on my PA Devices, is there a way to disable SSH password based authentication?
For a defined Administrators (Default admin excluded), you can check the option "Use only client certificate authentication (Web)" along with :Use Public Key Authentication (SSH)" this will virtually* disable the password based auth for ssh , but you would have to configure Cert-Based auth for WebUI logins :
virtually*= Password would still be prompted for admin if private key is not used during logins.
