PROFILE

Néfix Estrada

Nefix Estrada developed two core authentication features for the better-auth/better-auth repository over a two-month period, focusing on secure token handling and seamless user experiences. He implemented OIDC JWKS support with asymmetric signing for ID tokens, integrating JWKS endpoints with the OIDC Provider and JWT plugins to enable robust token verification and interoperability. Using TypeScript and leveraging skills in backend development and cryptography, he refactored core components, added comprehensive tests, and updated documentation. Additionally, he enabled OpenID Connect Silent Authentication by supporting the prompt=none flow, reducing friction for SSO in headless and mobile contexts and improving silent login reliability.
