Web3 Authentication

Definition ∞ Web3 Authentication refers to methods of verifying user identity and granting access to decentralized applications and services using cryptographic keys and blockchain technology. Unlike traditional Web2 authentication, which relies on centralized servers, Web3 authentication typically uses a digital wallet to sign transactions or messages, proving ownership of an address without revealing personal data. This approach offers enhanced privacy, security, and user control over their digital identity. It is a fundamental component of the decentralized web.
Context ∞ Web3 Authentication is a rapidly evolving area, with new protocols and wallet integrations constantly emerging to simplify user experience while maintaining security. News often covers advancements in wallet connect protocols, single sign-on solutions for decentralized applications, and the integration of self-sovereign identity principles. The goal is to make secure, decentralized access as seamless as traditional login methods.
