When a user logs on, he or she checks whether the logon ip address was previously logged on. for example, he modified the login function of our system during this time period. in order to be more secure, he or she added the mail verification function. When a user logs on, he or she determines whether the logon ip address has been previously logged on. if not, he or she needs to send a verification code to the mailbox and then enter the verification code he or she received before logging on, if the verification code is correct and the time does not exceed the specified time, you can log on and write down the ip address and time of the login. if you log on with this ip address later, you do not need to verify it. If the verification code expires, you must resend it. Verification error cannot be logged in. you need to re-enter the verification code or send a new verification code to your mailbox.
