What methods would you be considering for 2-step verification? Do you've any providers or APIs in mind for verification? If you could provide further information on how you wish to set this up we may be able to help further.
I agree -- I use "Authy" and others use "Google Authenticator" (cross-support). Almost every app out there uses these standards. Even cheapo sites have it (seems like a friendly SDK). Highly recommended!
Please add this feature!
I'm interested in this as well. I hope you can find time to add this, would make me feel much more comfortable with security.
This is still needed. It is way to easy for people to just run a program to try usernames/passwords on this site. Just the standard login for Google+Microsoft authentication would be a massive step forward
I agree. It is time for 2-factor authentication. The implications of someone getting access to one of our games on the GameSparks level are severe.
