Apple has essentially borked biometric authentication by implementing FaceID. Clearly it's pretty much worthless as a trustworthy security feature. So now it's back to entering 7 digit passcodes every damn time. Little did we ever suspect that the constant whining to minimize the bezels would lead to this.
The iPhone is de-evolving.
That might be true if you keep evidence of your criminal activity in your phone, AND, are arrested for a crime, AND, a judge signs a search warrant for law enforcement after being presented with probable cause your phone might contain evidence relating to your crime (assuming you live in the US and not entering the US at a border).
For others, FaceID is a great authentication method that strikes a good balance between security and ease of use.
If, however, you insist on keeping incriminating evidence of crimes you have committed in your phone, it's probably best to disable FaceID and instead use a seven digit passcode.
The good news is that Apple gives you options. Choose the correct option for your particular lifestyle.
