• For example, uppercase letters are automatically converted to lowercase and registered by the user.

  • This is true for all Auth0 database connection. When Auth0 DB is not the source of truth (for example, custom DB with import mode off) as well as other kinds of social enterprise connections where Auth0 is not the source of truth, the the email is retained as-is and not converted to lower case.
