Is it safe to start two-step verification?

Because Google's Gmail account is often attacked maliciously, I suggest that all users who use Gmail turn on two-step verification, so that security can be guaranteed. For two-step verification, it is recommended to use the Google Verifier installed on the smartphone to generate the verification code. Do not accept the verification code through SMS, because SMS can also be intercepted by operators, and the security is still not guaranteed. Below, the author will introduce the specific tutorial of two-step verification for Gmail users' reference. Two-step verification and dynamic password two-step verification mean that users need to enter a dynamic password of their mobile phone in addition to their user name and password when logging in to Google account, which adds an extra layer of protection to Google account. In other words, even if the intruder steals the user's Google password, he can't log in to the account because he can't use the user's mobile phone. Gmail's "two-step authentication" supports iPhone and Android phones, which is actually a dynamic password. Dynamic password, also known as one-time password, means that the user's password changes dynamically according to time or usage times, and each password is used only once. Because the password used every time must be generated by a dynamic token, and the password used by users is different every time, it is difficult for hackers to calculate the dynamic password that appears next time. However, dynamic passwords have higher requirements for mobile phones, and they need smart phones such as iPhone or Android. Install Two-Step Authentication For Gmail users who are frequently attacked, it is strongly recommended to use Gmail's "Two-Step Authentication" function. The setting method is to log in to Google account first, and then visit this address. After that, the system will let the user choose the way to obtain the verification code: SMS, voice phone or smartphone application. If the user's mobile phone is iPhone, Android or BlackBerry, it is strongly recommended to choose smart phone application, which is more stable and faster. Then go to iTunes or Android market to download an application called Google Authenticator, install it, and adjust the time of the mobile phone to the correct time before running. Then in Google Authenticator, click "+". Select a key according to the time type. Type the user's full email address in the account. Type the key generated on Google's web page in "key", with optional spaces, and then click "Finish". After that, you can use dynamic passwords, which greatly enhances the security of Gmail. After using two-step authentication and two-step authentication, the user's specific use process is that on the Web side, the user logs in to Google account and enters the original user name and password first. After that, the system will prompt the user to enter the dynamic verification code on the mobile phone. Users only need to open the Google Authenticator application on their mobile phones, enter the dynamic verification code displayed on the screen, and click OK to log in normally. In order to reduce the input times, users can choose to input the dynamic verification code every 30 days. For independent applications on mobile phones or desktops, such as Gmail Mobile Edition and Desktop Picasa, dynamic passwords cannot be used, and a random password needs to be generated in the "two-step authentication" settings of the application. In these independent applications, users need to use the random password generated by "two-step authentication" to log in to Google. Turn off two-step authentication If users find it too troublesome to use after enabling two-step authentication, they can choose to turn off two-step authentication. The way to turn it off is to visit the Use Two-Step Authentication page under Google Account Settings. Log in with user name, password and verification code, and click Close for two-step verification. A pop-up window will be displayed to confirm that the user wants to turn off two-step authentication. Click OK to close the two-step verification. Some users forget to pause the two-step verification when reinstalling the Google Verifier of their mobile phones, resulting in the inability to log in to Google. How to turn off two-step verification at this time? In this case, after logging in with a static password, click "Cannot use mobile phone" in the verification code input interface, and you can use: 1, the backup verification code. When using two-step authentication for the first time, users will be asked to print more than a dozen alternate verification codes and log in with any password in the printed file. 2. SMS. Google will generate a random verification code and send it to the user's mobile phone through SMS, and log in through this verification code. Mail is the core and key of password management. Users can get the passwords of most websites through the mailbox password reset function. So once the email password is hacked, the user's password system will be out of control. Although Gmail dynamic password seems a bit troublesome, it is not always entered, but can be re-entered on a single computer every 30 days. Convenience is good, but safety is more important. Users must pay attention to their password management. Although it adds a little inconvenience, you may avoid the possibility of huge losses.
