When I log in to : Trailhead.salesforce.com . I have been using the option : ':Log in with Facebook'. And I have a connected org with a username different than my facebook username. I have over 37000 points in Trailhead and around 28 badges. I do not want to change anything. I just want to log in to trailhead in my same account with everything same but without using the 'Log In With Facebook' option. I want to use the : "Log in with Salesforce"

Is there any solution?
