Better Auth migration

Layer / File(s) Summary
Better Auth foundation and server integration
apps/web/lib/better-auth/*, apps/web/lib/auth/*, apps/web/app/api/auth/*, apps/web/app/(ee)/api/*
Adds Better Auth configuration, plugins, hooks, session helpers, OAuth adapters, token utilities, authentication routes, cleanup routes, and server-session consumers.
Authentication flows and account management
apps/web/ui/auth/*, apps/web/app/app.dub.co/(auth)/*, apps/web/app/app.dub.co/(dashboard)/account/settings/security/*, apps/web/ui/account/*

Middleware, invitations, and application consumers
apps/web/lib/middleware/*, apps/web/lib/actions/*, apps/web/lib/api/*, apps/web/app/**/*invite*, apps/web/app/**/*onboarding*
Replaces legacy session access, narrows user contracts, migrates invitation tokens, removes legacy password endpoints, and updates authenticated workspace and partner flows.
Client session adoption and supporting updates
apps/web/app/**/*.tsx, apps/web/ui/**/*.tsx, apps/web/lib/swr/*, apps/web/prisma/schema/schema.prisma, apps/web/playwright/*, apps/web/.env.example, .github/workflows/playwright.yaml
Replaces NextAuth client hooks and providers, updates environment names and database indexes, seeds Better Auth accounts, and adds Better Auth Playwright API fixtures and tests.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to ea3c3

This migration currently exposes reusable session tokens and weakens authorization around email-change operations, while also breaking some OAuth continuation and authentication-related flows. These issues could enable account compromise or cause users to lose authentication progress, so the PR is not safe to merge until the security and correctness problems are fixed.

@devkiran, I reviewed the unresolved CodeRabbit threads and resolved four:

  • Admin impersonation now uses verified token data in the request context.
  • RATELIMIT_POLICIES has valid Record type syntax.
  • /request-password-reset has rate limiting.
  • The local useSession() wrapper provides the status compatibility adapter.

I kept these findings open because the current code does not address them:

  • Rate limit invalid API keys before hashing and database lookup.
  • Do not use plaintext API keys as rate-limit identifiers.
  • Add rate-limit headers to successful withSession responses.
  • Convert the millisecond reset timestamp before setting Retry-After.
  • Encode connect before redirect construction.
  • Reuse the in-flight SAML exchange request.
  • Consume both partner-account merge OTPs atomically.
  • Surface signOut failures.

Emit the fallback object to the stream.

If partialOutputStream yields nothing, this branch parses result.text into lastPartial but never calls stream.update. The code then validates and calls stream.done(), so the client resolves with no value and shows no reward. Update the stream after a successful fallback parse.

Use the repository Zod import convention.

Replace the named type import from zod with a namespace type import from zod/v4. This keeps the type import aligned with the repository’s Zod 4 contract.

Based on learnings: “In all TypeScript files under apps/web, import zod using a namespace import: import * as z from 'zod/v4' and avoid using named import: import { z } from 'zod'.”

Rate limiting still runs after the credential lookup.

authenticateApiKey hashes the bearer token and queries prisma.token before enforceRateLimit runs. An invalid key throws at Line 152, so unlimited invalid keys still force one hash plus one query each.


167-169: 🔒 Security & Privacy | ⚡ Quick win

The plaintext API key is still the rate-limit identifier.

Line 169 passes apiKey to enforceRateLimit, which writes it into an Upstash Redis key. Pass token.hashedKey instead, matching the value now used by updateApiKeyLastUsed.

Retry-After still carries a millisecond timestamp, and it is now sent on success.

reset is a Unix timestamp in milliseconds. Retry-After requires seconds or an HTTP date. These headers are also merged into successful responses at Lines 105-107, so every 200 response advertises a retry delay. Convert the value and set Retry-After only when success is false.

⚠️ Unverified finding

Confirm admin pages authorize independently of the Host header.

The gate depends on the Host request header. A caller can send a non-admin host to an auth endpoint and skip the workspace-membership check entirely.

- Around line 44-50: Update the session response construction in the route to
never expose row.token; return only an opaque session identifier for each
session. Add a server-side revocation handler that accepts that identifier,
verifies the session belongs to the authenticated user, retrieves the stored
token server-side, and passes it to Better Auth for revocation.

In `@apps/web/ui/auth/account-already-exists-modal.tsx`:
- Around line 47-53: Update the redirect query construction before router.push
to preserve the connect value by copying it into params, alongside the optional
email parameter, so the OAuth provider-link flow can resume after login.

Apply the same fix in `@apps/web/app/`(ee)/partners.dub.co/(dashboard)/auth.tsx at
line 45: The same continuation value is dropped during the onboarding redirect.

Do not return session bearer tokens to the browser.

The response includes the raw token for every non-current session. Any XSS payload can exfiltrate those tokens and reuse them outside the current browser session.

Return an opaque session ID. Add a server-side revocation handler that verifies ownership and passes the stored token to Better Auth.

Preserve the connect continuation across authentication redirects. Both this redirect and the onboarding redirect drop the connect query parameter. When either path is reached from the provider-link flow, sign-in cannot resume linking. Carry the encoded connect value into the destination query parameters in both locations.
