We're Living in a Passwordless World

The goal is to compel the use of biometrics and personal, always-on and always-online, devices (e.g. phones) that double as personal tracking devices.

To perform even mundane functions, you will need to provide biometrics (via scans) or check-in with a device tied to you. Facial recognition, gait recognition, etc. will catch anyone venturing about without a device or one genuinely powered down.

Once you're banned from a service or your access is reduced/restricted/modified in some undesirable way, for wrong-think or wrong-speech or stepping outside your house during a lockdown or straying beyond the borders of your designated ULEZ geofence or consuming too many meat calories over a certain period, there will be no way to create alt accounts and nobody else will dare to allow you to share their access or act on your behalf for fear of incurring the same penalties.

This is truly where we're heading unless enough people wake up and stop going with the 2 steps forward, 1 step back flow.
