How to enable two-step authentication for Google account

The so-called two-step authentication means that when you log in to Google account, you need to enter the dynamic password sent to you by Google through your mobile phone in addition to the user name and password as before, which undoubtedly adds an extra layer of protection and security to your Google account. In other words, even if a possible intruder steals or guesses your password, he can't log into the account because he can't use your mobile phone.

Since the account is safe, what are you waiting for? Quickly enable "two-step verification"! Here is a brief introduction to my own operation process, which is very good for your reference.

1. Log in to Google account.

Click Use Two-Step Authentication in the security bar.

Click Set Two-Step Verification in the figure below:

2. Set the verification method

There are two kinds, one is fixed-line or mobile phone verification; The other is a smartphone application:

If you are using Android, BlackBerry or iPhone, you can choose to use the authentication method of smart phone application, but you need to install one more application. Here I choose to use fixed-line or mobile phone authentication, that is, SMS authentication.

As shown in the above picture, fill in your mobile phone number. If there is one, a tick will be displayed next to it. In addition to SMS, you can also choose to use automatic voice message to receive the verification code. I will follow the default SMS mode. Click send code to start the test. If all goes well, you will receive Google's verification code. After entering the obtained verification code, click OK. If the verification code is correct, you will be prompted that the phone number has been configured. Enter the next step, and you will see the following interface:

Go on to the next step.

3. Add alternative verification methods

At this point, Google will provide you with a backup verification code of 10, which is the only way to log in when your mobile phone is lost or unavailable. This alternate verification code is very important, so be sure to save a copy:

In addition to backing up the verification code, Google will also ask us to add a backup mobile phone number. This spare mobile phone number can be a landline phone number or your friend's mobile phone number. The settings are the same as those in the second step above, but testing the phone has become an optional operation:

Continue to the next step, as follows:

This step is to confirm that some applications that need to log in to Google account cannot be used by receiving verification code, so you need to create application-specific passwords for them separately, so you can leave it alone for the time being (you can set it in your account at any time in the future) and go directly to the next step.

4. Turn on two-step verification

This is the last step, just click to open two-step verification, and then a prompt box will appear, and press the OK button. At this point, your Google account has completed the two-step verification setup process. In the future, if you want to log in to the account, you must enter the original user name and password, as well as the verification code received through your mobile phone. You may find it a little troublesome, but I think it's worth it. Safety comes first.

Finally, if you think it is really troublesome to enable two-step verification, don't worry. Google allows you to turn off this feature, log in to your account, and then click Use Two-Step Authentication. After entering, you can disable two-step verification if there is a setting.
