FAQPage Schema
How do I set up Replit OpenID Connect authentication in an Express backend?▼

Replit authentication in React Native is supported using expo-auth-session to handle the mobile OAuth flow securely. This Skill provides optional setup to configure Expo session storage and connect mobile clients to your Replit OIDC backend.

What database dependencies are required for Replit OIDC user sessions?▼

Replit OIDC user sessions require PostgreSQL to store authentication schema data. This Skill provides the necessary database schema and uses the pg library to handle session persistence alongside cookie-parser and express-session middleware.

Does Replit authentication use PKCE and how are CSRF attacks prevented?▼

Replit authentication enforces PKCE for the OIDC flow and uses state and nonce parameters to prevent CSRF attacks. This Skill ensures ID tokens are fully validated on the server for secure token handling.

Can I use Replit auth with a React Native mobile project?▼

Replit authentication in React Native is supported using expo-auth-session to handle the mobile OAuth flow securely. This Skill provides optional setup to configure Expo session storage and connect mobile clients to your Replit OIDC backend.

What is the best way to implement secure login for a Vite and React app deployed on Replit?▼

Secure login for Vite and React apps on Replit is best implemented using the platform's native OpenID Connect provider. This Skill streamlines that setup by providing the middleware, PKCE flow, and session management required out of the box.
