What can we expect from a password system that accepts images in addition to characters, particularly the images of episodic memory? The answer is the ability to volitionally manage many more passwords by our own remembrance.

1. What is Expanded Password System?
There are several known pictures.
I can easily find all of them right away.
Only I can select all of them correctly.
Practicable even in panic when images of episodic memory are registered
Incorporating the function of generating high-entropy online passwords from
hard-to-forget passwords
Security of real/cyber-fused society hinges on online identity assurance
Online identity assurance hinges on shared secrets, i.e. what we remember
