What is the second generation password protection? How to solve it?

The second generation password protection is a higher level of QQ security protection, as shown below.

1. Personal information

Personal information is your final right to interpret QQ. If you lose QQ, Tencent will let you change the new password even if the password-protected three questions and three answers and email address have been changed by others, as long as you provide the application time, application place and personal information.

Attention! Once personal information is rewritten, it cannot be changed. You can write photos or fake ones, as long as you can remember what you are writing now.

2. Secure mobile phones

This function was originally only available to members. The function of this function is that if you put your foot in front of the password, Tencent will send a free text message to the mobile phone number. Even if you are not in front of the computer, you can send instructions to Tencent's server so that you can reset your new password.

Note: 1. This service is completely free. 2. Your bound mobile phone number will not appear in your QQ data. 3. If you change to another number, ① the original number has been scrapped, and you can change your mobile phone number with confidential questions; If the original number can still be used normally, you can send instructions to Tencent's server, so you can also change the new mobile phone number!

3. Secure mailbox

This mailbox is the default mailbox when you perform a series of high-risk operations such as password retrieval. When filling in this email, it is recommended to write a real, effective and commonly used email (QQ email is recommended-QQ number comes with it).

Note: If you fill in the fake email address now, you need to provide the ID type, ID number and original email address when you retrieve the password. You can also change other email addresses to get your password back.

4. Security issues (DNA password protection

Whether you change your password or do other high-risk business, you basically have to answer one or two DNA questions and answers. Only when the questions and answers are correct can we continue to operate. It is recommended not to choose questions with uniform answers. You can choose, * * name, * * student number and * * place of birth.

Because "* * name" can enter English letters, and it is case-sensitive.

"* * Student ID" can be written in numbers as long as it is within the specified number of words, and "* * Native place" can be filled in Chinese characters.

In this way, your password protection materials include numbers, Chinese characters and English letters, and hackers are basically unable to start.

Password setting: It is recommended that passwords contain numbers, uppercase and lowercase letters and special symbols, such as:

83 $ 02 # 25 @ afSA & amp

If password protection is available, use password protection to retrieve the password.

But if not,

It can be handled through number appeal.
