SMS is still widely used to “prove” account ownership. But that “proof” has a market price.
According to the Cambridge Online Trust and Safety Index (COTSI), the average cost of fake SMS verification is:
🇯🇵 Japan: ~$4.93 🇦🇺 Australia: ~$3.24 🇺🇸 USA: ~$0.26 🇬🇧 UK: ~$0.10
When verification costs cents, fraud scales fast: fake sign-ups, account warming, gray marketplaces selling “verified” profiles, and account takeovers.

Today, trust is far more effective when built on adaptive multi-factor authentication. That means the system first evaluates context: device signals, behavior, login history, and risk level.
Biometrics aren’t just a “password replacement.” They tie a real person to a high-risk action. Especially when an attacker has already bought a phone number, bypassed SMS, or gained access via phishing.
At this stage, SMS often fails, but biometric identity verification — combined with liveness/deepfake detection, device control, and risk management — actually stops the attack.
- Low risk → no friction.
- Rising risk → step-up authentication via passkeys, hardware tokens, or biometrics (face, voice, fingerprint).
