Passkeys + SNA: The Evolution in Phishing-Resistant MFA

Learn how combining Passkeys with Silent Network Authentication (SNA) creates a phishing-proof, regulation-ready login experience without sacrificing recovery or usability.

Passkeys have redefined authentication by delivering a phishing-resistant, passwordless, and user-friendly solution. Yet, in regulated sectors such as banking, finance, and government, adoption faces hurdles – compliance requirements, recovery limitations, and dependency on platform providers. Meanwhile, legacy methods like SMS remain widespread despite severe security flaws, primarily due to their recovery capabilities.

Silent Network Authentication (SNA), offered by telecom providers, presents a promising complement to Passkeys. SNA verifies SIM card possession at the network level, enabling phishing-resistant step-up authentication, regulatory compliance, and enhanced recovery options. When combined, Passkeys and SNA form a robust multi-factor model, bolstering both security and user experience. Subscriber intelligence features, such as SIM reissue detection, further enhance fraud prevention.

This short presentation explores the integration of SNA with Passkeys, its benefits, limitations, and deployment considerations.
