Abstract: Disclosed are a method and apparatus for remembering passwords with the least amount of memory, overcoming the disadvantage that previously, passwords or fixed codes, such as credit card numbers, were inconvenient to record and difficult to remember. People's long-term memories regarding ethnic characters, letters, digits and patterns are used; one or two of the above are selected to intersect with blank units or information code matrices, the contents of which can be changed by characters to be set, so as to obtain coincident points and non-coincident points; according to the step of reading information thereabout as specified or according to the steps of filling in, confusing and re-finding fixed codes, passwords or the fixed codes are obtained; regarding a mechanical apparatus, a key, on which an imprint is left by means of pressing a character, can be expanded into long chains, two chains are matched to obtain more logic states, and a plurality of passwords are obtained by means of reading and segmentation as specified; regarding an electronic-type apparatus, three three-colour light-emitting diodes are connected to symmetrical switch buttons to form a matrix template; digits, capital letters and small letters and symbols to be set printed on the template are displayed; according to light colours of the light-emitting diodes and whether same are in a light-emitting state, information codes are arranged as specified; and a canonical character model ensures that the passwords or the fixed codes obtained every time are the same as those set before.
