This is why I submitted written authority to Qantas many years ago for the accounts I manage.
In my line of business I don’t bend the rules.
So why not just change all the phone numbers to your phone, so you get the SMS without having to bother the original account owner?
I really don't know why is everyone willing to lose so many body cells over this SMS?
80% of the general population knows how to use SMS authentication. 95% of the population doesn't know how to use keygen (hardware or app), nor Google authenticator.
IT picked SMS cos most people know how to use it, doomed (just look at the responses here). They implement something like app keygen, people would then complain because they use Windows Phones. They implement hardware keygen, and people complain they don't want to bring a piece of hardware. Worst of all, everytime something happens, it is IT who is made the evil people and they are hung out dry (on TV, radio, whatever).
Of course this SMS is annoying; but is losing all your points less annoying?
Of course there are more secure and easier to do this; but are you going to learn how to use it? Or are you just going to complain again?
People need to just put things into prospective, and look at the question here from EVERY angle, not just their own angle.
And, to round this out, kids are already stealing things from parents (read the ABC article I posted earlier in this thread), and it is getting the attention of TV newspapers and lawyers. If you guys are so against a tiny SMS, sure, let's just have 1 child steal some points from the parent's QF account, and let it go on TV. Qantas is going to lock down their system so hard, we are all going to regret fighting against this SMS thing.
Be VERY careful what you wish for.
