OAuth2 SSO with PKCE secures authorization flows for single-page apps by using code challenges instead of client secrets. Configure a PKCE client in Better Auth, implement the authorization callback to handle the code exchange, and retrieve user info via JWKS token verification to complete the integration.

Store OAuth tokens in httpOnly cookies to prevent XSS attacks from accessing them. Better Auth SSO handles this by managing token lifecycle server-side, ensuring tokens are never exposed to client-side JavaScript while maintaining secure session state.

JWT verification via JWKS retrieves the public keys from your authorization server's JWKS endpoint to cryptographically validate token signatures. Better Auth SSO automates this verification process, ensuring only tokens signed by your trusted issuer are accepted.

Yes, global logout across tenant apps orchestrates session termination by invalidating tokens and clearing sessions on all connected applications simultaneously. Better Auth SSO provides patterns to coordinate logout events across your tenant infrastructure.

Better Auth SSO implements OAuth 2.1 and OIDC standards, ensuring compatibility with standard-compliant authorization servers. This guarantees your Next.js app can integrate with any OIDC-compliant identity provider following current security best practices.
