Rollup ID

Plug it in, press build, and your app gains private-by-default sign-in without tracking. Start by creating an application with the CLI or dashboard, set your allowed redirect URLs, and pick a flow: Authorization Code with PKCE for single-page and mobile apps, standard code flow for server-rendered sites. Drop the ready UI component or wire your own form to the OIDC authorization and token endpoints. The provider speaks OIDC end to end, so your app stays portable. In Next.js, Express, or FastAPI, add the middleware to kick off login, process the callback, verify the ID token, and issue a secure session cookie. Scopes default to the bare minimum; request profile details only when you need them. For mobile, use the system browser with deep links; for desktop, use a loopback redirect. In local development, run the provider in Docker, use http callbacks on localhost, and let the tool rotate signing keys automatically.

Shape the sign-in journey to match your risk model. Offer passkeys with WebAuthn, email magic links, or classic passwords gated by TOTP when policy requires. The consent view shows exactly which claims you are asking for, enabling true data minimization. Start with a pseudonymous subject and progressively ask for email or name when a feature demands it. Tokens are short-lived; refresh is handled by the SDK with silent renewal. Export only the claims you need into your user store. Because the system is open source, you can self-host on your own infrastructure, audit every line, and keep telemetry disabled. No ads, no third-party trackers—just standards-based sign-in.

Protect your APIs and microservices with the same foundation. Validate access tokens against the issuer and audience, fetch the JWKS once and cache it, and reject expired or downgraded algorithms. Use drop-in middleware for Node, Go, or Python to guard routes. Model roles and fine-grained permissions as custom claims, and enforce RBAC or ABAC at the edge or in code. For service-to-service calls, issue client-credentials tokens scoped by resource indicators. Rotate keys on a schedule, pin token lifetimes per API, and use audit logs to trace who did what and when.

Operate with confidence from day one. Manage tenants, apps, and environments—dev, staging, prod—via CLI or Terraform, and generate clients during CI so screenshots and manual steps disappear. Connect external identity through OIDC federation to support enterprise SSO, or migrate from a legacy provider by linking accounts after email verification. Webhooks keep your systems in sync when a user signs up, resets a factor, or revokes a session. When something goes wrong, turn on debug mode, inspect end-to-end traces, and replay callbacks in a sandbox to reproduce issues. Whether you run it in a single container or a hardened cluster, Rollup ID gives you a practical, standards-driven path to private authentication.
