My main Auth0 hosted user database has usernames enabled, but we are slowly moving our users away from username based login to email address based login. Occasionally I have reason to create user accounts manually, and on those occasions I use the user’s email address as their
user.username. I went to create such a user today using one of my Auth0 CLI tools and I got the following error:
auth0.v3.exceptions.Auth0Error: 400: Username can only contain alphanumeric characters and '_', '+', '-', or '.'. Username should have between 3 and 32 characters.
No more ‘@’ sign? Have the syntax rules for usernames changed? Is this documented somewhere? I have many users whose
username is the email address.
