Is it mandatory to provide an alternate form-filling option rather than using Myinfo? Can Myinfo be the only form-filling option?

No, it is not mandatory to provide an alternate form-filling option besides Myinfo. Myinfo can be offered as the sole form-filling option. However, partners are encouraged to provide a manual alternative to accommodate and support users who prefer not to use Myinfo.
