Signal Signal 6: 92% of surveyed security chiefs have adopted or plan passwordless authentication

Summary

Deloitte's sixth watch signal treats biometric authentication as a next step in cybersecurity. Because AI can replicate voices, forge documents and mimic behavioural patterns, biometrics are becoming critical for verifying physical presence and identity. As deepfakes and AI-driven fraud grow more sophisticated, organisations are adopting biometric systems rapidly. In one study of chief information security officers, 92% said they have already implemented, are implementing or plan to implement passwordless authentication. The report cautions that biometrics will not be the only answer, since compromised biometric data cannot be changed like a password and privacy concerns remain significant. It expects hybrid approaches in which biometrics serve as the primary but not the exclusive method of verification.
