What does the time type of Harbin Bank SMS authentication mean?

Harbin bank SMS authentication time type refers to a way of identity authentication and security verification by receiving SMS verification code when doing some bank transactions. Under this authentication method, when a user makes a transaction, the bank will send a short message to the mobile phone registered by the user, which contains the verification code. Users need to enter the correct verification code within a certain period of time to complete the transaction. This way can increase the security of transactions and reduce the risk of fraud and theft. Generally speaking, banks will stipulate the effective time of SMS authentication, that is, users need to enter the verification code within the specified time. After this time, the verification code will be invalid and needs to be re-verified. Due to the different requirements of different banks and different transaction types, the specific time type of SMS authentication may be different. For specific transaction or service requirements, please consult Harbin Bank.
