Welcome!
It looks like you haven’t logged into your account in a really long time. We need to verify it’s you. To do so, we hope you still have that one thing that people frequently change after a really long time: your phone number! Obviously you can’t have moved or simply switched phone provider over the years, right?
We’ll send you an SMS, if you don’t receive it with the code, you can’t use your account any more.
Cheers!
