Account and security

Profile, sessions, passkeys, data export, and deletion.

Beginner walkthrough

Prerequisites: Read the two beginner guides below, finish Web local setup, and open this monorepo at its root in your editor. Web settings belong in apps/web/.env.local; Next.js does not read the root .env. /dashboard in the default fake mode is a no-database demo; /auth needs a migrated database.

Quick terms: a workspace is one team's separate users, data, and settings. The server is the trusted backend; keep provider keys out of browser and phone code. A migration is a versioned database change that creates or updates tables. An AI model is the engine that answers; the model catalog is the server's list of available model IDs and prices. A provider is an outside service such as an AI, email, or billing service. An entitlement is a grant that lets a workspace use a feature. A webhook is a message one service sends to another service's URL.

1. Sign in to /auth in two test browser sessions, then sign out from one session.

2. Request a protected page from the signed-out session; the server should require sign-in. This guide covers session behavior, not a cross-device session-revocation screen.

3. To inspect your own data export, use GET /api/account/export; it must not include another user's or workspace's private records.

For custom code, start with the supplied prompts/README.md and copy the closest prompt: prompts/new-app-screen.md for an app screen or prompts/new-landing-page.md for a public page. For server, database, or provider work, give your coding agent this guide's task and ask it to read AGENTS.md, .ai/PROJECT_CONTEXT.md, and matching .ai/ mirrors; inspect the exact source files named here; list files and checks before editing; preserve workspace ownership and server-only secrets; and show you the diff. Tell it the behavior you want, input and output fields, allowed roles, expected success and errors, and the test account, provider, or device. Use sample values; never paste a real secret.

Manage active sessions

Security settings expose the shipped session and credential controls through the selected auth engine. Revoking a session must invalidate server access, not only clear a local screen. Review web-settings-security.ts, the settings panels and auth runtime before extending them.

Export account data

The signed-in GET /api/account/export route provides the GDPR data export, including authored content. Keep access tied to the requesting identity and audit the shape whenever you add user-owned records. Never include provider tokens, signing secrets or another workspace's private data.

Verify account transitions

Test current-session sign-out, revoking another session, expiry, reauthentication and export access. Clear the previous account's cached presentation before rendering the next user's workspace.

Setup and configuration

Account surfaces live under /settings — general, security (password, sessions, passkeys), notifications, appearance, and audit. Each section reads server state and writes through server actions that re-verify the session.

Data export (src/data-export.ts) assembles a member's workspace-owned records; account deletion runs through the same ownership boundary. Both exist because privacy obligations are product requirements, not extras.

/settings/general        name, avatar, email
/settings/security        password, sessions, passkeys
/settings/notifications   per-category opt-outs
/settings/appearance      theme, density, layout

Implementation workflow

Keep security mutations re-authenticated where the provider supports it — password change, key rotation, deletion. Session listing must show the caller's own sessions only, and revocation must actually invalidate the token.

Export only data the member owns — reuse the workspace-scoped repositories rather than ad-hoc queries. Deletion ordering matters: revoke sessions and clear dependent records before removing the account row.

Verification and troubleshooting

Verify a revoked session loses access immediately, an export contains the member's records and not another workspace's, and deletion leaves no orphaned ownership rows. Test passkey ceremonies only on HTTPS origins.

Frequently asked questions

14 questions

What is supastack?

supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so you can focus on product-specific features.

Does it support web and mobile?

Yes. supastack includes Next.js and Expo apps as starting points for web and mobile experiences.

What authentication is included?

Better Auth covers email OTP, magic-link, and social sign-in; email/password stays available at the API layer and through the Auth.js credentials engine for products that need it. Personal workspaces are provisioned with the account so product records stay scoped from day one.

How does it support AI?

supastack includes configurable multi-provider AI, usage tracking, budgets, and encrypted bring-your-own-key support.

How are subscriptions handled?

For products built on the kit, Stripe billing, subscriptions, and entitlements form the paid-access foundation. Provider secrets stay server-only.

Where does my product-specific code live?

Product-specific features remain in a separate codebase while the product configures and integrates supastack’s foundation modules.

How does supastack pricing work?

The kit is a one-time purchase with lifetime updates: One Platform at $249 (temporary launch price, $100 off the regular $349) — your pick of Next.js (Web), Expo (iOS & Android), or Tauri (macOS & Windows Desktop) — or the All Platforms Bundle at $499 (temporary launch price, $100 off the regular $599) with every platform and the full monorepo, plus $75 per extra developer seat. No kit subscription. Checkout on this site delivers your license key by email, with repository access via GitHub invite.

How do workspaces scope my data?

User-owned records are scoped by workspaceId. Identity, entitlements, AI usage, billing events, and audit entries stay inside the personal workspace boundary.

How do background jobs work?

Trigger.dev is the explicit job runtime. The JobRunner contract only promises enqueue, status, and cancel—workflow semantics stay Trigger.dev-specific and explicit.

How is email different from outreach?

Transactional email covers product workflows such as completion notices. Cold outreach and campaigns are product concerns outside this kit’s email module.

How do mobile purchases work?

Mobile includes native purchases and restore through RevenueCat, with access verified by your server. Configure the store accounts and complete device testing before release. Web billing remains separate.

Where do AI provider keys live?

Bring-your-own-key credentials are encrypted and stay server-only. Keys are redacted from logs; usage and budgets remain visible at the workspace level.

Which payment methods does checkout accept?

The Stripe-hosted checkout accepts cards and can also offer Alipay and WeChat Pay once those wallets are enabled on the Stripe account — handy for buyers in China. Wallet authorizations confirm asynchronously, so the license page updates as soon as the payment clears.

Can I get a refund?

After you've got access to the repository, supastack is yours forever, so it cannot be refunded. But rest assured, you get the complete source code with lifetime updates to build and ship unlimited products for yourself or clients. You just cannot resell the code or redistribute the repository as a starter kit or template.
