What security is in place for dApps and stolen private keys?

I’m not so worried about me because I know how to keep my keys safe. But in a world were grandpas are using Peepeth and CryptoKitties, what precautions are/will be in place to make the theft of peoples key or passphrase not mean the compete take over of all their accounts?
