The invention provides a dynamic password electronic lock system in which a password changes according to random codes. The system is composed of a lock body and a temporary password generator. A fixed password of a password lock is stored in a nonvolatile storage of the lock body, when a temporary user uses the electronic lock, the electronic lock generates the random codes R, a temporary password used for unlocking is obtained through calculation of the fixed password and the random codes according to a special algorithm (such as a one-way hash function), and automatic calculable changing is performed on the temporary password along with changes of the fixed password or differences of the random codes generates each time. Thus, the temporary password can be obtained through calculation when a password lock manager mastering the fixed password in the password lock receives the random codes, and after the system is delivered to the temporary password lock user, the temporary password lock user can perform unlocking through the temporary password in an effective period of time.
