Good day to you...

I didn't find any document mentioning Telnet login security for MVPs... am I right?

Well you can't setup on MVP same setup system as on master, but you can allow/disallow telnet server in MVP (go in Setup Pages -> Protected and then you have a button to allow/disallow telnet access to MVP

When answering supporting calls, or even fixing something without going to the clients place, I use Telnet to go to the setup page, so turning it OFF will get me stuck.... Won't be able to Re-enable it again.

Telnet is also working over USB!!
For this, the panel is not required to be set to USB connection mode, but you need to have installed the AMX USBLan Driver on your PC. The USBLanLink tool establishes a virtual network card on your PC with IP address 10.0.0.1 by default. The panel is running on IP 10.0.0.2.

So just connect a Modero panel by USB with your PC, launch a telnet session to 10.0.0.2 and have fun :-)

From time to time I find that my MVPs stop communicating with their masters. If the master can't contact the TP, there is no way to send a SETUP command to the TP. Some nice telnet features (that don't disturb active users) are:
GET CONNECTION to verify that the panel is pointed to the correct master
SHOW CONNECTION LOG to see network reliability
GET IP when your TP has a DNS entry rather than static IP

I would like to see improved telnet security across the whole G4 range. (I use MVPs and CV7s.) At this point in time, anyone can telnet into my panels and reboot them, change IP settings, etc. A simple username/password (or even just a PIN) would be suitable.
