Ted Burg Prompted for login, not accepted
I am on the Quickstart create your first app, the step to use Chrome developer tools to simulate salesforce1. It prompts me to log in (that isn't shown in trailhead) but doesn't accept my login. Am I someone else in trailhead playground? I wasn't asked to create a new login and password with trailhead playground...
If you have done your work in the trailhead playground then when it prompts to login provide trailhead playground credentials.
Please refer below link and get the trailhead playground credentials.
