Okay so there might be some security risks if people are stupid and don't know how to adequately protect their account info. Does that mean the rest of us shouldn't enjoy some convenience because of the stupid people out there? There is an inherent risk in everything and you can't fix stupid.

In games where I never had the option of an authenticator none of my accounts were ever hacked. Why? Because I'm not stupid. I never gave out my account info to any program, I never followed any e-mail links to phishing sites, I never gave my account info to apps.

Also I would imagine if SE made a mobile authenticator app, they would take measures to remedy these issues should they arise. Nothing is unhackable, nothing is entirely foolproof, nothing is 100% secure. Let those of us who aren't idiots make use of the convenience of such an app.
