Summary

SMS One-Time Passwords (OTPs) have been widely used for multi-factor authentication but are increasingly seen as inadequate due to vulnerabilities such as phishing, SIM-swapping, and interception, which undermine security. In contrast, FIDO2, which includes WebAuthn and CTAP2, offers a more secure, phishing-resistant, and user-friendly authentication method by utilizing public-key cryptography, thereby significantly enhancing digital security. Transitioning to FIDO2 involves strategic planning, including API integration and managing credential lifecycles to ensure a smooth migration. Didit, with its AI-native platform, supports this transition by offering robust identity verification tools, such as ID Verification and Passive & Active Liveness, which enhance user onboarding and authentication processes. These tools, along with NFC Verification for ePassports and eIDs, provide a high level of security, helping organizations build a strong security framework that protects against evolving threats.
