I have user access to a server which enables SSH access through passwords. However, I want to disable that access for my own user and only connect through a RSA key. I don't have root access to the server. Is there a way to achieve this?

Thank you, R.

    While you can't delete your own password to disable password based logins, and you can't edit the sshd_config file to disable password authentication for yourself, you could create a massively long password for yourself if you can't manage to get this disabled. I'm assuming security is your motivator when stating this. – Spooler Oct 4 '16 at 8:13
  • Yes, you're right, it might be an idea. Thanks! – rhobincu Oct 4 '16 at 9:04

No you can't. You can request the administrator to disable password based logins for your specific account though by having them set in the /etc/ssh/sshd_config:

Match user rhobincu
   PasswordAuthentication no
