What is the function of SMS verification code?

We added SMS verification procedures when registering websites and paying in banks. The user receives the verification code through the mobile phone, which ensures the authenticity of the information filled in by the user, and also provides a new verification procedure for the user to pay to a certain extent, which plays a role in informing and vigilance. With the popularity of smart phones, we need to register more and more things. Almost every day, I will receive SMS verification codes from banks, websites, clients, ticketing companies and other fields. Seemingly a series of insignificant numbers, but inadvertently decided all aspects of our lives.

After docking, the system can automatically send the verification code, which is fast, can respond within 10-30 seconds, and can reach the arrival rate of 100%. This verification method is very convenient for all fields, which is also the main reason why people like SMS verification code. Watch the back door. What should I pay attention to when using SMS verification code?

First, pay attention to SMS interception. Many mobile phones have the function of intercepting harassing messages, which can help us easily intercept all kinds of spam messages such as advertisements and promotions. However, the side effects of interception function are also very obvious. In order to improve the interception ability, many short messages sent by non-whitelisted mobile phone numbers will be intercepted, and the SMS verification code is likely to be shot. If you can't use SMS verification, it is likely to give a thief who is stealing your bank card a certain time, and at the same time, you can't realize the early warning function without receiving the verification code. Therefore, it is suggested that when using SMS interception, you should look through the intercepted messages regularly and be careful of being shot in the SMS verification code.

Second, beware of mobile phone viruses. Android mobile phone virus is widely distributed and rampant at present. One of the main purposes of many mobile phone viruses when stealing bank card information is to intercept the verification code and forward it. Hackers aim at your bank account and will retrieve the password by SMS. At this time, the bank will send a short message verification code, and the virus will intercept the verification code in the background and send it to the designated mobile phone, so it is easy to put out your alarm and easily get through the back door you set. For mobile phone viruses, it is recommended not to Root, do not install cracking software, choose a formal application market and install anti-virus software.

Third: Don't tell others about the verification code. Although this is funny, there are not a few users who tell others the SMS verification code. For some aunts who don't know what the verification code is, scammers use this short board to cheat, and recruiters are not uncommon. Therefore, it is suggested to popularize middle-aged and elderly people who do not know how to use scientific and technological products, so as not to be fooled.

Fourth: beware of verification code harassment. As we mentioned earlier, SMS interception, in fact, some SMS verification codes are sent from formal channels, and some people use this loophole to harass others with SMS. A software called "SMS Bomb" can realize verification code harassment.

As long as the other party knows your number, you can use the principle of sending verification code to harass you. The software can collect verification codes from different websites and then send verification codes from different channels to your mobile phone. Blocking through the blacklist is invalid because it comes from different numbers. This kind of thing is hard to avoid. I suggest you try not to disclose your information.

SMS verification code has become a part of our life, which provides us with convenience but also has certain risks. So I suggest you pay attention to the use of SMS verification code, and don't turn convenience into trouble.
