The FSA ID allows students and parents to identify themselves electronically to access Federal Student Aid websites.
The FSA ID allows students and parents to electronically sign the FAFSA
An FSA ID is made up of a username and password and can be used to log into the online Free Application for Federal Student Aid (FAFSA®) form.
While you aren’t required to have an FSA ID to complete and submit a FAFSA form, it’s the fastest way to sign your application and have it processed. It’s also the only way to access or correct your information online, or to prefill an online FAFSA form with information from your previous year’s FAFSA form.
