One time password Authenticator - Mobile App?

[Ziyyigo-Tipyigo]

but smartphones have alot of security software available,

"Available" is not the same as "in use."

if an app doesn't have permission to access certain features it cannot,

Most people just click through the default settings.

example if the FFXIV app doesn't need network access it can never be manipulated to access the internet.

Super Happy Awesome Funtime XIV app will use your own character for the hourly /panic dance show if you just give it your login info! Be the first kid on your block!

Sure, such a phone app is (probably) better than nothing (for now). But it cannot and will never be as secure as something you'd need a screwdriver and soldering iron to get inside of.
