GoDaddy is now allowing its international customers to enable 2 factor text message authentication for their accounts. I shared all of the details that were given to me in a blog post this afternoon: http://www.domaininvesting.com/godaddy-now-offering-international-2-factor-authentication/
They should use Google Authenticator / Authy kind of apps to reduce their SMS charges. JMO. Edit: Finally we got 2 factor authentication. Thanks
