Why do campus flash messages need to get the password again every time they log in?

In order to prevent the number from being stolen and multiple users using the same account, and to ensure that the interests of legitimate customers are not harmed, the digital campus platform dynamically changes the password of the SMS customer account. The way to obtain the dynamic password is that the customer sends "mm" to 106593005 (0. 1 yuan/piece, which can be included in the package containing short messages) using the telecom mobile phone in the package, and the password is valid for 28 hours. If you don't receive the password message, you can bring your valid ID card to the campus direct store to reset it. If customers don't want to use dynamic passwords, they can also bring their valid identity documents to the campus direct store and set them as static passwords. Customers should keep the static password properly to prevent theft. For more service benefits, click "official website" below to answer your questions.
