What is a bank dynamic password?

The bank dynamic password is a combination of numbers and letters, and there are several numbers in it, usually 6 to 8 digits, in order to confirm that the owner himself is operating. This password is random and dynamic, and it needs to be entered within a specified time to take effect.

Because this dynamic password can be changed at any time, it is not a fixed password, so it cannot be cracked in theory. As long as the mobile phone is not lost, the password is only known by the owner, that is, the cardholder, and the personal information security of the customer can be guaranteed.

Usually this password is valid for 1-5 minutes, which is a relatively safe protection measure. If it is not entered within the specified time, it will be invalid, which can effectively protect the information security of users and users can use it with confidence. But there are conditions to ensure the safety of customers: to ensure that bank cards, passwords and mobile phones are not stolen at the same time.

According to a special algorithm, a time-dependent and unpredictable random number combination is generated every 60 seconds. When users authenticate, they must enter a dynamic password in addition to the account number and static password. Only through the system verification can you log in or trade normally, thus effectively ensuring the legitimacy and uniqueness of the user's identity.
