What is a universal verification code?

The general verification code is 888888,123456,000000, etc.

There is no fixed universal verification code, because the use of universal verification code may be different according to application scenarios and purposes. In addition, the general verification code is usually set and managed by developers according to the requirements of specific applications, so there is no unified general verification code standard. If you need to use a universal verification code, it is recommended that you consult the relevant application developers or administrators for specific verification code information.

However, there are some special circumstances. In order to verify or remember the password conveniently during development, the client will save the account number and password, and splice the universal verification code, such as 888888,123456,000000, to meet the requirements of splicing calls and login requests.
