    If you already have a device set up,  a page showing your two-step authentication devices displays. Click Add a device.
  5. On the Setup a new device page, click Landline.
  6. On the Landline Phone Setup page enter your phone number, extension (if applicable) and name of the device.
    If this is an international phone number, click the International number? link and select a country. Click continue.

    enter phone number and assign a name to this device
  7. If you want your landline to be your default device, click Yes, make <device name> my default.

    select whether or not to make this landline your default device
  8. A confirmation that you have successfully set up your landline for two-step authentication displays. Click Done to exit.
