Hi All,
Very Good Morning!
Can any one tell me how you guys completed this 2 factor authentication  for users login challenge in trail head as the user name with which they need to verify is being shown as error.
When i tried to create a new user with user name sthripio@jedeye-tech.com as per challange it throws error says the user already exist. Can some one help?
 

Hello everyone, I've been working on this challenge in the Date Security portion of Trailhead for some time but need some help (See below)

The challenge requires a profile to be created with the following traits:
    Name: Account Reviewer
    Salesforce license type
    Only read access to Account object. (And no access to any other object in the Org)

Understand that I did read the indepth reading before hand and I created a read-only clone profile in the Accounts profile list but am stuck as how to proceed from there. Challenge error states: Challenge not yet complete ... here's what's wrong: The 'Account Reviewer' profile does not work as expected. Please Advise.
