What does this have to do with using a strong password?

McAfee's device was far from being "unhackable". It's just marketing from someone who only cares about money and shilling shitcoins.

Actually, according to Ryan Castellucci's article called "Bitfi's hardware wallet is terrible" and CoinTelegraph's article, the device is basically a cheap stripped down Android phone that looks like the WarpWallet and generates a brain wallet password. And all of this will 'only' cost you $120.
