Access is via files in a ".zip" file, including a program file that is customized to contain your credentials.
No installation is required; you just extract the contents of the ".zip" file into the same new folder that you made for the ".zip" file. You open access by opening a ".bat" file that uses IDEAFARM.COM to validate the hash of the program file and then opens that program. For zero-trust usage, you do all of this within a virtual machine so that the program has no access to your computer.
