i-Hacked.com explains how to reprogram a portable road sign:
** HACKER TIPS ** Should it ask you for a password. Try “DOTS”, the default password.
In all likelihood, the crew will not have changed it. However if they did, never fear. Hold “Control” and “Shift” and while holding, enter “DIPY”. This will reset the sign and reset the password to “DOTS” in the process. You’re in!
Good to know. Not that anyone would ever actually do this. That would be wrong.
It does illustrate that physical access trumps password security. Almost every password-protected device has a reset button that resets the password to a factory default. Both the reset procedure and the default password are available in the manual, which is on the manufacturer’s web site.
