After 8 billion there was a high pitch noise that makes me want to punch the creator of the video.
Why on earth would someone put that noise in there... "Let's add a really annoying noise into a video that is supposed to get us customers"...

Anyways, the part where they went wrong is that you can't memorize passwords.  You can, and they can still be secure, if you come up with something good enough...
There's multiple ways to go about this, so I won't go into it.

Biometrics aren't entirely secure either, no usable system is secure.  In one of the examples, a women had her credit card stolen, or account hacked neither have much to do with passwords.  Accounts are often hacked using phishing or MITM techniques (the latter is becoming increasingly rare), and credit cards can be stolen in many ways that have absolutely nothing to do with passwords.

Overall, I've seen worse, but this could've been better.

The noise is supposed to be a form of mind control that turns your mind into mush so you buy their products without realizing what happened.
