The invention relates to a device for verifying passwords, comprising a verifying unit and a displaying device. The verifying device is used for verifying passwords by comparing passwords inputted by an inputting unit and preregistered passwords. If the inputted content comprises the preregistered passwords or a password group which is formed by adding false passwords to true passwords according to the preset rule, the password passes the verification. The true passwords can be letters or numbers or special characters of the registered passwords, and the false password can be letters or numbers or special characters inputted randomly by the user or the combination of any two of the letters, the numbers or the special characters. The displaying device is used for displaying the content inputted by the inputting unit. When the registered passwords which are simple and are easy to remember are used, random passwords can be added to front and the rear of the true passwords according to the preset rule, thus the problem that the registered passwords are saw stealthily can be solved, and the psychological burden of inputting the registered passwords in the public place can be reduced. The method for verifying the passwords does not need to convert or remember again the dynamic passwords, thereby being easy to master. The device for verifying the password is easy to implement when being applied to an electronic product such as the automated teller machine (ATM) of the bank or a mechanical structure such as a full-mechanical dialing plate type password lock.
