I login to Trailhead w/ Facebook connect as I don't have a Salesforce account (in early implementation). When completing the Trailhead exercise requiring Data.com Assessment, you must authenticate w/ Salesforce credentials from the App Exchange. (1) I don't have standard User Name / Password since I use FB Connect; (2) It doesn't have the same FB Connect option, (3) I have tried putting in my Resourceful Badger User ID and clicking Forgot Password but nothing ever arrives. Any ideas?
