Which attribute is confirmed as not being required for a default Okta user profile?

The attribute confirmed as not being required for a default Okta user profile is the Display Name. In the context of Okta user profiles, the essential attributes for creating a user generally include Login and Primary Email, as they are critical for user authentication and communication. The Display Name, on the other hand, is considered more of a supplemental attribute, which can enhance user experience by providing a recognizable identifier for the users but does not impact core functionality.

While Login and Primary Email serve pivotal roles within the identity management processes—Login being the username needed to access Okta and Primary Email being necessary for account verification and password resets—the Display Name is optional and can be populated based on organizational needs. Therefore, it's possible to have an Okta profile without a Display Name, making it clear why it is not a required attribute.
