Parents

Which parents do I include on my CSS Profile? What if my parents are divorced/separated?
How do I know if CSS Profile is required from both of my biological/adoptive parents if they are divorced/separated?
Why would a parent need their own account log-in, and how do they create it?
What if I do not have contact with my non-custodial parent?
Are stepparents/my parent’s partners included?
Is parent data secure? How is data transmitted?
