Hi Everyone,
We are evaluating 2 methods at this time. SMS, and Yubikey.
The "free subscription" we're referring to is SMS verification. Unfortunately we're a prime target for SMS flooding if we make this a free service, as you can probably understand.
As for the Yubikey, you will pay for a key and the service itself would of course be offered free of charge, making it effectively a one time fee.
So there would be no monthly fee? Please verify.
