Empowering Decentralised Authentication

Amidst the rise of decentralised social platforms (DeSo), concerns over data ownership and privacy have sparked interest in alternative authentication methods. Web3Auth takes a step forward by integrating Farcaster into its SDKs, offering users greater control over their digital identities.

Seamless Authentication with Farcaster

Farcaster, now available as a social login option, allows users to authenticate with Web3Auth through a simple configuration process. Utilising FIP-11, users can log in using Farcaster clients by scanning a QR code and granting permission for the application to access their sign-in information. Once verified, users receive a self-custodial Web3Auth wallet for signing messages and transactions within the application.

Enhanced Integration Across Platforms

The integration extends to Web3Auth's Plug-and-Play Modal and NoModal SDKs, alongside other login methods like Google and Discord. This seamless integration enhances user experience while prioritising security and decentralisation.

The Technical Workflow

Under the hood, the Web3Auth SDK establishes a channel with the Farcaster client via the Farcaster relayer, facilitating communication between the user's device and the application. The process involves displaying a QR code on the Web3Auth frontend, which users scan using their mobile device and approve via Warpcast. Upon approval, Warpcast generates a signature, which is then verified by the Web3Auth SIWF server to generate an app-scoped JWT token. This token is used for authentication, ensuring secure access to the user's Farcaster account information.

Future Developments

Looking ahead, Web3Auth plans to deepen the integration with Farcaster, enabling applications to not only read but also write data to the protocol. This move reflects Web3Auth's commitment to advancing decentralised authentication solutions and empowering users in the evolving digital landscape.
