[junhaoliao]

Issue description
The New VNC Password field allows only 6-8 characters.

Steps to reproduce the issue

1. Select "Reset VNC" and enter more than 8 characters in the "New VNC Password"
2. Click on "Connect"

What's the expected result?

• The VNC password will be trimmed to 8 characters and encoded using "vncpasswd".

What's the actual result?

• A warning windows pops up and doesn't allow the user to reset VNC with this length of password.

Additional details / screenshot

• "vncpasswd" also trims any user input password down to 8 characters. I believe the prompt should only be a warning but not an error(disallowed operation).
