Unique "username" for all users

Hi @sazzer ,

Thank you for providing additional context about this query.

Since you prefer to have a user-editable attribute, I suggest you create an attribute (let’s say username) under the app_metadata attribute and use app_metadata.username as the unique identifier.

Here are a few FAQs that explain the app_metadata attributes.
