Biometrics are relatively convenient and very safe when they're used in place (not remotely) with a human agent overseeing. No cops have ever let a suspect pop out to buy a 3D printer and some custom moulds before taking their prints. The airbase's gate guard isn't going to let you substitute a custom-made adversarial JPEG image for your face after asking you to roll down the window even though her normal job is statistical analysis and she has never fired that weapon she's carrying in anger.

They're not great without supervision and they're completely hopeless remotely.
