How can you set user password to blank/null ?

 

The user interface asks for something other than blank/space

Why would you want to? This would potentially weaken security. Now any guest who comes in your internal network has the potential to change and poke around your server WebUI.

 

I think this is why there's a limit..

Or cracks your router's WiFi password to gain access to your internal network while sitting out on the street (or in the house next door)...

 

Google for tools to do such a thing and the time required to break that 'protection'!  It is easier than you think...

 

Plus, when you login via a terminal session as root, you don't need a password to gain command line access to your server.  And, in case you don't know, command line access as root to a Linux/UNIX system is the Holy Grail for a hacker!  He becomes the owner of your computer!!!  (You only supply the hardware...)

Thanks John_M, I'll check the link.

 

Thanks Frank1940/ideaman924 for the heads-up.

 

I'm running some tests, so I'm needing a blank password. Nothing permanent
