Can anyone at Harvard- Faculty, Administrator, Staff, Students- register in HUFP?

Yes. Anyone with a valid HUID can register in HUFP. First time registrants will be led through a brief registration process where they will be asked their name and email address before being returned to the portal. After this process every time a valid HUID holder logs in to the system they will pass through the HUID PIN page to complete their log in.
