In trying to protect against unsolicited form submissions, I checked the box "Require phone authentication" in my "Settings." I was indeed prompted to authenticate in ODK Collect when trying to "Get Blank Form" from my list. However, it won't accept my username and the password I use to log in to formhub.org. Is there another set of credentials I am supposed to be using?
The same problem occurs when trying to connect to http://formhub.org/arthur/formList in a desktop web browser.
