Maximum number of times to obtain verification code of electronic health code

There is an upper limit to the number of times you can get a verification code.

The number of times the mobile phone obtains the verification code exceeds the limit, so it is recommended to obtain the verification code again the next day (after zero), because the number of times each account receives the system verification code every day is limited. After the number of times the system sends the verification code exceeds the limit, it will not be able to send the verification code again to prevent malicious changes to the account security information.

Verification code is a public automatic program, which is used to distinguish whether the user is a computer or a person. It can prevent malicious password opening, ticket brushing and forum flooding, and effectively prevent a hacker from constantly trying to log in to a specific registered user in a violent way with a specific program. In fact, using verification code is a popular way for many websites now, and we have realized this function in a relatively simple way.
