Most of the current authentication is based on the centralized OAuth and SMTP protocol framework. These protocol frameworks will make the authentication service providers become centralized collectors of user Web2-Web3 information (although this is not their intention). This massive collection of user data poses a significant risk of exposing the user's identity and assets, ultimately compromising the security and privacy of Web3. DAuth is an improved and adapted version of OAuth for the Web3 ecosystem, providing native privacy and trustless social account access for wallets, decentralized identifiers (DIDs), and decentralized applications (dapps).
