Dynamic Cryptography Knowledge Dialysis
Dynamic passwords are also called temporary or offline passwords to solve

intelligent lock restores the original administrator password and time
information through decryption algorithm.
According to the above principle, if you want to use dynamic password
normally, you must meet two conditions: manage password and time, so you
need to enter the correct management password of intelligent lock. And
need to synchronize the time of intelligent lock and network time or
within error range, please refer to the operation instructions of
intelligent lock.
Note: in order to distinguish the "temporary password" in the Internet of

"also refers to" dynamic password ".
Enter administrative password
The management password follows the following rules.
