ABSTRACT:
The present invention is related to a method for verifying authorized access, and is specifically a method for verifying authorized access with an improved means of inputting a password, so as to prevent a spectator observing the inputting process from learning the password, and to facilitate memorizing the password. In said method, a user memorizes as a ‘user-friendly’ password, in relation to a reference background predetermined by the user, at least one locations as assignable districts, their order, and their number, but inputs the password by inputting codes that are shown at locations of the assignable districts consisting the memorized password. These codes are randomly determined and shown to the user, so that the codes as password change each time whenever the user asks to enter the system.
