During this period, we have modified the login function of our system. In order to be more secure, we have added a verification function for sending emails. When the user logs in, it is judged whether the login IP has been logged in before. If not, a verification code needs to be sent to the mailbox, and then the received verification code is entered before logging in. If the verification code is correct and the time does not exceed the specified time, you can Log in, and note the IP and time of this login. If you log in with this IP in the future, you will not need to verify it. If the time exceeds, the verification code becomes invalid and needs to be sent again.
