Why does my CF have to enter the verification code every time I log in? How can we eliminate this phenomenon?

It is possible that there is no error in the verification code you entered, but there is still an error, which may be one of the following two situations:

First of all, the page refresh problem.

The verification code of the login page will change with each refresh. If the system prompts you that the verification code is wrong, the system will change the verification code. Is this a possible page or a previous verification code? In other words, you will not enter the same registration code twice. After seeing the verification code change, just re-enter a new verification code.

Second, the full/half angle problem of input method

The full-angle and half-angle input numbers in the input method are different, that is, the full-angle number 1234 and the half-angle number 1234 are different. Captcha input only supports half-width digits, and the input is full-width digits. Although the figures are correct, they still cannot be verified.

In addition, with the gradual increase of new users, the system must be upgraded and maintained frequently. Some unexpected problems are normal, and some users will be affected.
