We are rushing to replace easily forgotten passwords with biometric authentication—using our faces, fingerprints, and voices as the ultimate unhackable keys to our digital lives.

As we bind our biological selves permanently to our digital security, we face a chilling question: are we building a safer digital world, or are we walking into an irreversible trap where a single security failure means losing control of our actual physical identity forever?
