Securing Digital Identities: The Power of Hybrid Authentication

Current authentication systems rely on password management and third-party identity providers, some offering 2FA and biometric authentication. However, vulnerabilities persist, including single points of failure, data breaches, and replay attacks.

Public-key cryptography systems are gaining popularity with decentralized ledgers and blockchains for digital identities and assets. They address centralization risks and third-party reliance but require users to manage private keys responsibly.

Advancements like Ethereum’s ERC-4337 (Account Abstraction) now enable seamless integration of mainstream and decentralized authentication. These innovations support identity recovery and compatibility with protocols like OpenID Connect.

i2CAT will showcase a hybrid authentication system combining traditional email/password authentication with account abstraction, public-key cryptography, and smart wallets, offering enhanced security and flexibility.
