What if the computer sends a verification code?

1. Can I send a verification code to my mobile phone when I log in?

What you said is not very detailed. First of all, you need to know the meaning of verification code. Please make it clear that the verification code can be divided into temporary and permanent.

First of all, I want to talk about the conditions for the appearance of verification codes. In fact, it is also very simple, that is, the server of (TX) judges whether your qq is abnormal according to certain conditions. Judging from my experience of hanging up qq for such a long time, this condition is whether the ip address changes greatly in a short period of time to judge whether this QQ is abnormal. Of course, this anomaly also includes a large number of login with wrong password, repeated login and so on. I only said ip changes, and everything else is very simple.

Once, my main number was registered in my office (point A). I didn't turn off qq normally when I turned it off, but turned it off directly. Then I went home (point B) and immediately logged into Q, and the verification code got stuck. Log in again the next day, and the verification code disappears.

Is this the illusion for Teng Xun? The number is logged in at point B and also at point A (ip has changed greatly in a short time)? Then judge the abnormality, add a temporary verification code to test it, and log in normally the next day, so you don't need a verification code. The above example illustrates the reason why the temporary verification code appears, that is, the ip address changes greatly, but it can be restored to the address before the change, and the verification code disappears, which also illustrates the temporary nature of this verification code.

Another time, my machine was hanging Q, and suddenly the power went out and the phone called back. More than 85% of my numbers need verification code after booting. Close Tenyqq and log in after ten minutes. There is no verification code. For another example, my office initially used Netcom's network. Later, for various reasons, I changed the telecommunications network and changed the network. After that, 95% of my QQ that doesn't need verification code needs verification.

I copied it and went home to log in again, and I didn't need a verification code. The ip addresses of Netcom and Telecom are quite different. I want to use this example to illustrate the persistence of verification codes. The permanent verification code mostly appears on the black number and the 9-digit number of the new application. Why? Your black number used to be in other areas, but now you are logged in this area. The ip has changed a lot and has not been restored, so you have been adding verification code.

These 9 new application numbers are generally the numbers restored by Teng Xun. Because the previous owner and the current owner of this number logged in in different places, the verification code appeared. I have a lot of black numbers affixed with verification codes. )

To sum up: verification codes can be divided into permanent and temporary, and dialectically, they can be converted to each other. The above example can also be considered in this way. If I change the network, I will always use the telecommunications network, so there will definitely be a verification code in the * *, which will become permanent. If I find a verification code in the telecom and I hang it at home, there will be no verification code, which means I find that the verification code with verification code in the telecom is temporary.

Of course, mitnick's post only talks about how to deal with temporary verification codes, not how to deal with permanent verification codes. I can definitely say that as long as I can find the ip address segment used to log in before the verification code appears in this number and use that segment as a proxy, the verification code will definitely disappear. Solution: 1: Change QQ information address to local address. 2: Log in locally 2-3 times. 3: Log in by mobile phone 1 time. Log in every two days. You will be surprised to find that the verification code does not exist.

2. The laptop can't send the verification code when it is connected to the public network.

1. Reset DNS, open the start menu, find "Attachments" and find "Command Prompt" in "Attachments".

2. Run the command prompt as an administrator.

3. Enter the command "ipconfig /flushdns" to reset dns.

4. Then check IE settings. Open IE and click Tools in the upper right corner. Select "Internal Options".

5. Click "Connect" and select "LAN Settings"

6. Put "√" before "Use automatic configuration script", and then click "OK".

7. If it still doesn't work, restart the modem. If you access the Internet through a router and a modem, they can both be turned off and restarted.

3. What should I do if I always send messages with verification codes?

If you always send various verification codes, consider the following questions:

In order to achieve the effect of harassment and deception, it is possible that the number given to you by the seller has been harassed by SMS bombs through related software. SMS Bomb is to send repeated spam messages to mobile phone numbers through special software.

It is recommended that you download and install professional anti-virus software for real-time monitoring and intercept related spam messages. It is a malicious act of human harassment through software.

This is a short message bomb, that is, someone maliciously registers with your mobile phone number and then lets you receive various verification codes. Generally, anyone who knows your mobile phone number can.

(3) Some people use SMS bombing software. Enter the information of your mobile phone registration website and send the verification code. You can apply for customer service shielding, but it may have an impact on subsequent use.

When the mobile phone has various verification codes, it is recommended not to reply to anyone's own verification code. If the number is bound to a bank card, Alipay, etc. , need special attention.

4. Computer login to qq requires mobile phone to send verification code. How to cancel it?

When we log in to QQ by computer, the computer QQ will prompt "The current device needs authentication, please open the QQ mobile version to confirm".

At this time, mobile phone authentication is needed. If "Allow Login to QQ" is selected, there will be no prompt when logging in in the future. If you select "Login only once", you need mobile phone authentication every time.

For security reasons, I choose to log in only once. Of course, if I accidentally click "Allow login to QQ", I won't be prompted every time I log in, because this is a mistake. How do you want to make QQ prompt? , click on the penguin head in the upper left corner.

Click Settings in the lower left corner to enter the Settings interface.

Click the "device lock, account security" option to enter the interface.

Just click the computer icon and delete it. The next time you log in, the phone will prompt you as it did the first time.

5. Every time the computer logs in Taobao, it needs to send a verification code to 106575258 196. How to cancel?

Just turn off login protection.

The method is as follows:

Log in to my Taobao-Account Management-Security Settings-Operation Protection Settings, click Maintenance, find the login protection of Taobao webpage, click Close, and select the verification method to cancel (as shown below).

The login protection function of Taobao webpage means that when Taobao members log in to Taobao, they need to conduct secondary verification by any means such as mobile phone or digital certificate after entering the correct password, and they can successfully log in after passing the verification. This function can be used for free.
