Secure applications may include two or more factors; a common example is the "PIN and chip" system used with credit cards, where you need both the card and secret code to authorize a transaction. Many online services now provide two-factor authentication to protect against password-based attacks. 28-factor authentication would likely be very secure in theory but also so impractical that it would be unusable. The user will need to prove their identity 28 different ways which would be so time consuming that would outweigh the convenience of a smart phone.
