The Free Application for Federal Student Aid (FAFSA) is the form that students in the United States must complete to apply for federal student financial aid. A FSA ID is a username and password that you use to access your FAFSA online account. You will need to create a FSA ID before you can apply for federal student aid.
To create a FSA ID, you will need to provide your name, Social Security number, date of birth, and email address. You will also need to create a password. Once you have created a FSA ID, you can use it to log in to your FAFSA online account and complete the FAFSA form.
