使用短信进行两步验证
您可以将移动设备设置为接收仅限一次性使用的 6 位数代码，该代码在您登录账户时通过短信发送到您的移动设备。除了其他凭据外，您还需要手动输入此代码。
步骤：
在 Shopify 后台，点击您的用户名和账户图片。
点击管理账户 > 安全。
选择短信发送，然后点击下一步。
选择国家/地区代码，然后输入您的电话号码。
点击发送身份验证代码。
查看手机上的短信。
从短信中检索 6 位数代码，然后在验证代码中输入该代码。
在密码确认下输入您的密码，然后点击启用。
请妥善保存您的恢复代码，万一您无法访问移动设备时可以使用。请确保将恢复代码离线保存到可通过多种方式访问的安全位置，例如移动设备、台式电脑和打印出的文档。
现在，当您尝试登录时，将需要使用移动设备进行两步验证。
您可以将其他电话号码添加为备用验证方法。

Two-step authentication using SMS text messages
You can set up your mobile device to receive a one-time six-digit code that is sent in a SMS text message to your mobile device when you log in to your account. You'll need to manually enter this code in addition to your other credentials.
Steps:
From your Shopify admin, click your username and account picture.
Click Manage account > Security.
In the Two-step authentication section, click Turn on two-step.
Select SMS delivery, and then click Next.
Select a country code, and then enter your phone number.
Click Send authentication code.
Check your mobile phone for an SMS text message.
Retrieve the six-digit code from the text message, and enter it then under Authentication code.
Enter your password under Password confirmation, and then click Enable.
Save your recovery codes in case you lose access to your mobile device. Make sure that you store them in a safe location offline that you can access in multiple ways, such as from your mobile device, your desktop computer, and from a printed document.
Now when you try to log in, you require your mobile device for two-step authentication.
You can add a different phone number as a backup authentication method.
