Seems like an obvious thing that should be done to prevent any accidents.

Especially sensible given that this is Morostide and we might accidently press something :).

The best way to prevent any accident is to be careful and read what is written on the buttons, actually.

Well there is already a "safety" on the pet section (confirmation page, similar to the v1 zapper) and I have a hard time feeling bad for someone if they decide to hit the avatar one, since it's really obvious.

I thought PIN numbers were more of a precaution against hackers.

I support this idea. You don't have to check off that PIN option if you don't want it. I use more PIN inputs than my sister does on her account for instance.
