Complete password- and key-less login for user using SSH

I want to use this plugin in my text editor to debug my HHVM application. Therefore I need a Linux user which is able to login via SSH both without password and without key authentication.

How can I achieve this?

I tried several ways, including

passwd -d hhvm-debuguser

But then, I can’t login; I entered nothing when I was being asked for password:

main@faraway:~$ su hhvm-debuguser
Password:
su: Authentication failure

My SSH config file looks like this, only allowing the user hhvm-debuguser from my personal IP:

DenyUsers hhvm-debuguser

Match User hhvm-debuguser Address my.ip.address.home
    PermitEmptyPasswords yes
    PasswordAuthentication yes
    AllowUsers hhvm-debuguser

(Yes, I know that this is an absolute edge-use-case which should not be used in the wild and I'm aware of the risks and security isses)

therefore I need ... without key authentication. I don't follow why this plugin requires no key authentication. – Paul – 2015-08-28T00:37:05.847

Reading the readme file under your link, you need to set up passwordless login, it doesn't matter if passwords are still enabled, and you don't want to denyUser in shh config. What it wants is to be able to login without a password. – Tyson – 2015-08-28T00:55:23.553
