Am I fucked? Parents can't electronically sign

I'm just gonna be honest, they can't verify who they are online because they're undocumented. In 21 and their need to electronically sign has pretty much made it impossible because their own made accounts can't be verified. Is it still possible to send in a signature and how would I be able to? I usually find the link but I haven't unless they changed it how. What's worse is I don't particularly recieve aid from them but fafsa doesn't consider me independent.
