Are you able to remember and recall the relations between accounts and the corresponding passwords?
The Expanded Password System that accepts images provides a solution to this hard problem. When unique matrices of images are allocated to different accounts with the EPS, those unique matrices of images will be telling you what images you could pick up as your passwords.

Passwords & corresponding accounts
1. Passwords &
Corresponding Accounts
Being able to recall strong passwords is one thing. Being able to recall the
relations between accounts and the corresponding passwords is another.
↓
We are often obliged to
- reuse the same passwords across many accounts
- carry a memo with passwords and the corresponding accounts on it
- depend excessively on a password manager with a single point of failure
however strongly we are told not to.
2. Biometric products do not help for this
problem because biometric solutions
require a password to be registered in
case of false rejection.
No Help from
Password-Dependent Solutions
Neither do the multi-factor
authentications which require a
password as one of the factors.
3. Expanded Password System that accepts images provides a solution to this
hard problem. When unique matrices of images are allocated to different
accounts with the EPS, those unique matrices of images will be telling you what
images you could pick up as your passwords.
Here is The Solution
The EPS will free us from the burden of managing the relations between
accounts and the corresponding passwords.
Account A Account B Account C Account D
Account E,
F, G, H, I, J,
K, L-----------
4. At the root of the password headache is the cognitive phenomena
called “interference of memory”, by which we cannot firmly remember
more than 5 text passwords on average. What worries us is not the
password, but the textual password. The textual memory is only a
small part of what we remember.
We could think of making use of the larger part of our memory that is
less subject to interference of memory. More attention could be paid to
the efforts of expanding the password system to include images,
particularly KNOWN images, in addition to characters.
