In order to ensure your security, your phone number is required. Your number is used in a number of processes to verify that you are the one making a transaction or logging into a new device.

We first have you enter your phone number and then send you a code via SMS. You will input the code texted to you to verify your phone.

After that point, anytime verification may be needed you will receive an SMS on your phone.

We do not recommend using Google Voice or other VoIP providers.
