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 an 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.
- 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.
Enter your password, and then click Next.
From the Authentication method list, select SMS delivery.
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 then enter it under CHECK YOUR PHONE.
Click Turn on.
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 phone for two-step authentication.
You can add one or more different phone numbers as a backup authentication method.
