I don’t know if you have been used to fill in the mobile phone number to get the verification code in the registration process, because from time to time you don’t receive text messages and then give up. Or just turn around and walk away from the registration process because of the tedious process. Operations that waste time are an insult to users who are increasingly anxious about time fragmentation. In other words, when designing the sign-up process, don’t expect too much from your users. They don’t intend to spend too much time on sign-up.

As we enter the second half of the Internet, especially with the advent of 5G, SMS authentication, a form of authentication that people love and hate, is slowly moving out of center stage. What caused its inevitable departure? Let’s take a look at the operation mechanism of SMS verification code.

1. Encrypt the verification code and send it

Click the “send verification code” in the App to send A request to the background. The background receives the request, generates the verification code A and decompiles it into the SMS verification code A’, requests the SMS service provider to send the SMS verification code A’ to the user’s mobile phone, and stores the verification code A in the background database.

2. Verification code decryption verification

After receiving the SMS verification code A’, the user submits the SMS verification code. After receiving the request, the background decompiles the SMS verification code A’ to verify whether the decompile result is verification code A. If yes, the verification code is successful and the user’s registration application is successful.

This brings three problems, one is the security risk, the second is the time cost, the third is the cost of SMS.

First of all, under the mechanism of SMS verification code can be brute force cracking can also be SMS sniffing, the equipment cost is not more than 300, and the economic loss caused is uncountable. Secondly, due to the tight channel resources, the actual arrival rate of SMS verification code is generally only 60%-70%. It is also common for users to wait for more than ten minutes when the channel is crowded during holidays and holidays. Billing way to finally, message authentication code is just send to collect fees, if meet the hacker in a mobile phone number send message authentication code list cycle, if did not make any restrictions, so the App to lose tens of thousands or more SMS charges, and if it is no use sending a text message of most, the bigger the user registration capital expenditures, These are unnecessary losses.

The essence of business is actually a 4P model: product, channel, promotion, price. And the priority of these points is in descending order. For an App to be successful, it needs to do these things in turn. If others have done well in one area, you must do well in that area and do better in the next area. Therefore, when SMS authentication has exposed many disadvantages, if you want to take the App to a higher level, you should choose a more fluent, safer and more convenient authentication method from the user’s perspective.

Like one-click login. What is one-click login? One-click login is authenticated directly by accurately identifying the user’s mobile phone number in the process of login through the carrier’s unique communication gateway number retrieval technology. Users can register and log in by entering their mobile phone number to access information and services within the app, which takes less than three seconds. If you compare it to SMS captcha, it is much more powerful in terms of convenience. Because the integration of the three major operators gateway authentication capabilities, so there is no need to worry about being hijacked. And cost, a key login only verification success will be charged, the heart silently read one hundred times: save is to earn…

As the current situation of the Internet solves more and more problems, more and more boundaries, a lot of functional models have been conventionalized norms, to stand out from the need to develop more creative space. Captcha will leave center stage on the Internet for the foreseeable future. Instead, there will be a more secure and convenient one-click login.
