I am also in need of the user name and password. We have a Gmc 84211-1 that we are only able to access the display and not change setpoints. We have not been able to find the password. I would greatly appreciate any help.

Information
The basic user/pass for GCMs & LCMs is:
user
pass
But there is a backdoor code that can be used, but I have forgotten it 10 years ago when I used to work on these devices.
The backdoor user is BCFLD, but I don't remember how to figure out the password.

Backdoor
I think since the year 2000 upgrade, which was rev 5.0 or higher, the backdoor stopped working.

Backdoor still works
I just spoke with someone here at work, and he informed me it still works.
He just used it a few months ago with one of our older customers.
The formula just changed after 2000.
I just did a search on Google, and found the code.
Can't post it here because I don't want to be banned for posting proprietary information, but someone did post it many years ago on a website.
Have fun.
