Is that because it’s two digits?

No, because the default is to present you 3 numbers and asks you which your number is!

1 in 3 and easy to hit by mistake.

Shouldn't there be a button like "i didn't request this" or something? Why would you hit one of the buttons if you know the request is bogus?

You've never hit the wrong button by mistake on a phone touchscreen?

I can only envy your adroitness.

That's insane.
