When we look at these lock codes,
something I always like to ask people
is, which do you think is the strongest?
Do you think a face scan, biometric scan, fingerprint,
or is it simply a really complex passcode, or a swipe,
otherwise known as the gesture?
In reality, your biometric lock is
the weakest if you set a four-digit PIN or a gesture
behind it.
If you have a complex passcode that backs it up, great.
Some people say, what if I don't have a backup for a biometric?
Everyone does.
So think about this.
If I-- even think of COVID.
When you started wearing masks, your phone
no longer recognizes your face.
So imagine, if your phone never recognized your face again,
how are you going to get into it?
It will prompt you eventually for your PIN or your passcode.
So your biometric lock is as strong as the PIN,
the passcode, or the gesture pattern that's behind it.
If the device is hot when it arrives in your hands
or at your lab, it's because it's
in a state where it can unlock with a fingerprint or some kind
of retina, face, or other scan--
the biometric scans.
Guessing the passcodes could wipe the Android device,
so you never want to do that.
But if it is a gesture--
which is rare.
I have not come across any Android device that's actually
using a pattern in a long time.
That is the easiest to crack because there's
only so many options.
And some people think, isn't a four-digit PIN easier?
It could be, but not necessarily.
Something else that Android does that is confusing
is look at the PIN.
Do you notice how it doesn't just have four dots?
On an iPhone, it prompts you for how long
it wants that password to be.
Is it a four-digit PIN?
Is it a six-digit PIN?
On Android, it could be one number.
It could be seven numbers.
There's no indicator to you on how this is going to look.
