input the password again”
, to the user through the user interface, and waiting to receive the password input by the user;
wherein the hardware processor further performs following steps using the instructions;
when detecting that the first near field communication module finishes sending the near field communication label data when the valid time is reached, judging, by the first password management module, whether the password generation module stores the generated password, and deleting the stored password if the generated password is stored;
wherein the user terminal is comprised in a password-based authentication system comprising a password-based trading terminal, wherein the password-based trading terminal comprises a second near field communication module, a password authorization module, and a second non-transitory computer readable storage medium, and a second hardware processor performing instructions stored in the non-transitory second computer readable storage medium;
the second hardware processor performing following steps using the instructions of the non-transitory second computer readable storage medium;
restoring, by the second near field communication module, near field communication label data sent by the user terminal through near field communication to the password and then sending to the password authorization module; and
verifying, by the password authorization module, validity of the password from the second near field communication module;
the password-based trading terminal further comprises a second password management module, wherein the second hardware processor further performs the following step using the instructions;
after knowing that the password authorization module finishes a verification, deleting, by the second password management module, the verified password stored in the password authorization module.

Abstract
A user terminal, a password-based trading terminal, a system and a method for password-based authentication are provided. Wherein, the user terminal comprises a password generation module and a first near field communication module. The password generation module is configured to generate a password. The first near field communication module is configured to convert the generated password into near field communication label data, and then send the data to a password-based trading terminal through near field communication. The present application effectively ensures password security during the password-based authentication.
