@btme0011 we appreciate the effort and contribution, but this is the expected behavior. All this details are optional to allow you to simulate different type of users through different login methods (email+password, phone, magic URL, anonymous and more).

It is always best to open an issue and discuss before investing time in making a PR. That said, great job with the code implementation.
