I am trying to complete this trailhead challenge - setting up external identity . I am not able to find the "External Identity User" profile in any of my orgs, even thought they use custom domains and identity for Internal Users. Is there something that needs to be done in order to enable this profile/User License?
You have to sign up for a new developer org(https://developer.salesforce.com). After this goto setup and search profiles. You can see this
