If someone does not want to remember a passphrase then it goes to something they have. Either some sort of key digital or "analog" or biometric. Granted changing that is more limited but some get creative, 10 fingers and 10 toes to choose from.
I don't think there is any perfect system. Passwords are easy to change but also easy to forget. Biometrics are hard to "lose" but also hard to change.
