someone could build a login sequence that uses yes/no questions that only you know the answer to. Then it would just be a matter of how many bits of protection you want. eg: 32 questions would be something like 32 bits of entropy. Kind of laborious but also fairly secure because the order and selection of questions could be randomized, so someone would have to shoulder surf many questions in order to break in. eg: Is this your mom? (with a picture). Is this your favorite color (a color showing). Is this your phone number? Is this your house? Do you like cheese? Do you like candy crush (ok, no entropy there, the answer is always "yes") . now, does someone want to make this product?
