Passcode ID vs Touch ID vs Face ID vs Sweat ID (Future).
Which one is the best ? and what will you chose given an option

I got this Que. in mind while reading @mothered 's post on 'Cops Are Hacking iPhones With Secretive $15,000 GrayKey'.

I will never choose touch id, face id and don't know about sweat. sounds new.

Passcode can only be remembered. Via a single individual, you can leave hand prints to unlock a safe (Reference from Fast and Furious 5). Via leaving your hand prints on a cup can still be used to authenticate a lock.
For a face, all you will need is either a professional makeup artist or, capturing a screenshot of the target, then able to utilize the face for a clearer view.

When it comes down to a passcode, no one can capture you and, get your prints or nothing, they will need your brain to open a safe. for example: If you were to kill yourself, no one can open that safe without the digits.

In terms of fingerprint authentication, I've stated my thoughts (and facts) already In my thread. Here's the excerpt of that post:

Allow me to briefly comment on (biometric) fingerprint authentication and the reasons you should not have It enabled. Because fingerprint scanners are so small, they only take "partial prints", hence full human fingerprints are next to Impossible to match. As such, the device will store around (example) 10 fingerprint Images- just to make It easier to find a match. A finger swipe only has to match "one partial stored Image", thus a mismatch can happen with anyone's print.
Furthermore, law enforcement agencies can obtain a warrant and force the user to unlock the phone. They can't force you to remember the numeric code, can they?

I'll be here all day If I elaborate on everything In question, so I'll do nothing of the sort. I will however, state the following.

As with almost every from of authentication, the "Recovery" Is weakest point of security. The forefront has no relevance. For example, on some fingerprint authentication devices, after ex-amount of Invalid authentication attempts, the device with prompt for a numeric password- of which this Is the "recovery option". Essentially, you're not attempting to bypass the fingerprint authentication, but more so purposely hit Invalid logins to access the numeric password. This defeats the purpose of having FA In It's entirety.

The pass-code option is the most secure out of all of these, because a pass-code is stored in your brain (which is only accessible to you), and the other options are stored outside of your brain (on your body), and some kind of authority could easily force you to unlock your device with your face and fingerprints sitting right on you.

and some kind of authority could easily force you to unlock your device with your fingerprints sitting right on you.

Agree.

Moreover, law enforcement agencies have millions of fingerprint records at their disposal. As mentioned above, because fingerprint scanners only take partial prints, through s systematic approach, any one of those records can match the "partial" print and unlock the device.
