How can I set up an "Offline User" account?

I am working on a survey and want to use the Offline App.
I read under troubleshooting that "Some accounts have difficulty logging in due to the number of surveys in the account. If your account has over 100 surveys, you are at risk. You’ll typically see an error message stating, ‘API Error: We were unable to retrieve data from our servers. Please ensure that you have a good internet connection and correct account permissions.’ To mitigate this issue, many organizations create ‘Offline User’ accounts that are used strictly for offline surveys. By collaborating the surveys to these accounts, they can easily be used to collect responses that filter into the original account.”
Does anyone have experience setting up one of these “Offline User” accounts?
Thank you!
