An estimated 1% or so of the population is suspected to have DID, and memory gaps don't exclusively work like "some identity knows the password but it's not me"

An estimated 1% or so of the population is suspected to have DID, and memory gaps don't exclusively work like "some identity knows the password but it's not me". I can totally forget things without someone else in the system still knowing them. Nobody really has to hold the memory for it to become inaccessible.
