What should I pay attention to when choosing SMS verification code?

Please pay attention to the following questions:

1. Length of SMS verification code. Generally speaking, the verification code of mobile phones in the industry is composed of 4 to 6 random numbers. Why the length of mobile phone verification code is 4 or 6 digits, the key is due to system optimization and human temporary memory. For example, the application device must try to decrypt the 4-digit SMS verification code to the 4th power of 10 and try to decrypt the 6-digit SMS verification code to the 6th power of 10. The validity period of mobile phone verification code enterprises is generally around 1 minute. Therefore, the authentication length of the mobile phone verification code enterprise can be said to be safe enough, and there is no need to set the verification code too long in case everyone can't remember what the verification code is.

2. The valid time of the mobile phone verification code. When the enterprise encounters congestion or other unexpected situations, some customers may not receive the SMS verification code, so customers generally need to receive the verification code again. However, if the effective time of SMS verification code is not set at this time, it is likely to cause resource consumption. Because the last authentication has not expired, the content of SMS authentication is consistent. However, if the mobile phone verification code enterprise sets the effective time for scientific research, even if there is some delay, it will not affect all normal calibration and certification.

3. The total number of mobile phone verification codes and SMS verification codes sent by enterprises. When designing mobile phone verification code, please don't forget to increase the limited frequency of "receiving verification code". If it is not restricted, it will not only lead to consumption, but also prevent illegal people from intentionally clicking frequently, which will continue to affect all normal customers' actual operations. Therefore, for the same IP, it is necessary to increase the transmission frequency of the same mobile phone number in the same period. For example, the same mobile phone number is only received three times in 24 hours. After three times, the system software will remind you to try again after 24 hours.

4. SMS verification code is charged by enterprises, and the price of SMS verification code is very low. However, if the company needs too many SMS verification codes and needs to push many SMS verification codes every day, then the cost problem must be carefully considered. Therefore, before applying SMS verification code, sales staff should compare several SMS mass sending platforms and enterprises with higher selective prices.

SMS verification code can not be ignored, because the arrival rate and sending speed of SMS verification code directly affect the number of registered customers. On the road of choosing SMS verification code, Bian Xiao has pointed out the direction for everyone, so don't go in the wrong direction!
