feat(core): add sendMagicLink and verifyMagicLink API - #297
This pull request adds passwordless magic-link authentication to the stateful strategy. Applications can email users a verification link and establish a session when they verify its token.
Key Changes
Add the sendMagicLink and verifyMagicLink APIs and register the POST /signIn/magicLink and GET /signIn/magicLink/verify endpoints.
Add magicLinks configuration for token expiry, sign-up permission, and the email callback. Tokens expire after 30 minutes by default.
Add magic-link account and verification-token types, plus adapter support for revoking tokens.
Add rate limits for sending and verifying links. The stateless strategy reports both operations as unsupported.
Add tests for API and endpoint flows, redirects, sign-up settings, and invalid tokens.
Usage
Configure the email callback, then call the programmatic API:
This change adds magic-link configuration, token and session handling, public APIs, and HTTP endpoints. Sending creates a verification token and can deliver an email. Verification can mark an email as verified, create a magic-link account when needed, and create a session. Stateless handlers report both operations as unsupported.
Adds magic-link account and token types, API and session-strategy contracts, configuration, response schemas, and persistence enum values. The context validates and carries the configuration. The Prisma adapter adds token revocation operations.
Stateful token and session handling packages/core/src/session/stateful/*, packages/core/src/session/stateless/*
The stateful strategy creates tokens and verification URLs, then verifies eligible tokens and creates sessions. The stateless strategy exposes both operations as unsupported.
API and endpoint flows packages/core/src/api/*, packages/core/src/actions/signIn/magicLink/*, packages/core/src/config/router.ts, packages/core/src/shared/rate-limiter.ts, packages/core/src/config/logger/catalog.ts
Adds send and verify API flows and HTTP endpoints. The flows apply rate limits, invoke the session strategy, handle email delivery or cookies, and resolve redirects. The API factory exposes both methods.
Flow validation and supporting records packages/core/test/api/stateful/*magic-link.test.ts, packages/core/test/actions/signIn/magicLink/*, packages/core/test/config/magic-link.test.ts, packages/core/test/setup/entities.ts, packages/core/CHANGELOG.md
Adds API, endpoint, and configuration tests, magic-link fixtures, and changelog entries. The shared API validation result uses origin instead of originURL.

Merge Risk: Moderate · up to 44d0a
Magic-link sign-in is added, but several issues should be resolved before merge. The emailed link's origin can come from the request, a link preview can consume the token before the user clicks, and the response reveals whether an account exists. Magic-link sessions also default to 30 days instead of the documented 15.

Assert the persisted tokenHash in the send success test.
The success test checks only that createToken was called. It does not check the tokenHash argument. sendMagicLink stores createHash(token), and verification looks up the token by hash. A change to the stored hash would still pass this test. Every delivered link would then fail verification. The sibling forgot-password.test.ts checks the hash argument, and this test can do the same.
Suggested fix for the first success test
import { describe, test, expect, vi } from "vitest"
+import { createHash } from "@/shared/crypto.ts"
import { authInstance } from "@test/setup/auth.ts"

Assert the session and CSRF cookies in the verify success test.
The success test checks headers: expect.any(Headers), which matches any Headers object. Removing either setCookie call in verify-magic-link.ts still passes this test. Without the session cookie, the browser does not stay signed in. Without the CSRF cookie, later CSRF-protected requests fail.
Read both values from output.headers with getSetCookie from @/shared/http/cookie.ts. Use the session and CSRF cookie names that the test instance configures. getSetCookie throws when the cookie is absent, so the assertion fails when either setCookie call is removed.

Add expired and revoked magic_link token tests to verifyMagicLink.
The failure tests cover an unknown token and a wrong token type. No test covers a magic_link token with expiresAt in the past or with revokedAt set. The verifier rejects both cases before it revokes the token or creates a session. A change that removes either check would not fail this suite.
Add one test for each case in packages/core/test/api/stateful/verify-magic-link.test.ts. Each test should assert the public failure result and that createSession is not called, as the existing failure tests do.

Assert the Location header for the redirectTo=/check-email request.
The test checks the status, the JSON body, and the mock calls. It does not check response headers. The JSON body sets redirectURL: null because the server handles the redirect. The Location header is the only response field that carries the destination. A regression that drops or changes that header while the status stays 302 would still pass this test.
For this request, /check-email passes isRelativeURL and is returned unchanged. resolveApiRedirect then sets Location on the HeadersBuilder, and toResponse returns those headers.

Consume the magic-link token only on a state-changing request, not on GET.
GET /signIn/magicLink/verify passes every valid token to verifyMagicLink. The stateful handler revokes the token on the first valid request and creates a session. Link preview and email scanner requests send this GET before the recipient opens the link. The recipient's later click then gets HTTP 200 with { success: false, redirect: false, redirectURL: null }, and no session is created.
Direction: the GET should only show a confirmation step and must not revoke the token or create a session. A separate POST to the same path should consume the token and create the session. The current code has no such split, so this change needs a new handler and route behavior.

A database initialized at 7006cc10406d0cda4e49d7078111c7d9d89f5f65 records the old migration name, so Prisma treats the renamed file as pending. Applying it attempts to recreate existing objects, beginning with CREATE TYPE "UserStatus", and the migration fails before adding magic_link.

user, so a newly sent link cannot be revoked by an overlapping verification.
Preserve revocation of older live magic-link tokens.
- Around line 24-25: Update verifyMagicLink to load the user associated with
verifiedToken and reject the link if the user is missing or their current email
does not match verifiedToken.identifier. Perform this check before creating a
session.
- Line 18: Update the verifyMagicLink flow so GET validation only displays a
confirmation page and does not revoke the token; consume the token and create
the session only after an explicit POST confirmation. Do not automatically issue
replacement tokens for revoked tokens.
- Around line 18-22: Update the magic-link verification flow around
`revokeToken` to use an adapter-level atomic operation that consumes the token
and creates the account/device and session as one unit. Remove the separate
writes from this flow so any failure leaves the token and related records
unchanged; do not restore the token with a compensating write.
Review comments at @packages/core/src/shared/utils/api.ts:
- Line 92: Update the origin selection for output.origin via getOriginURL so
magic-link URLs use a configured base URL or an origin validated against
trustedOrigins; do not trust the incoming request origin by default, and reject
the request when neither a configured nor trusted origin is available.

- Around line 1-29: Preserve the existing initialization migration in both
Prisma migration trees instead of renaming or replacing it. Add a separate
upgrade migration with additive enum changes for `AccountType` and

recreating existing types or tables.

Review comments at @packages/core/src/session/stateful/verify-magic-link.ts:
- Around line 19-20: Add a test for the valid-token path in verifyMagicLink
where revokeToken returns false; assert the result has success: false and
createSession is not called. Keep the existing successful-revocation coverage
unchanged.
Review comments at @packages/core/test/api/stateful/send-magic-link.test.ts:
- Around line 81-91: In the new-user API test for sendMagicLink, assert that
createUserMock receives the requested email, new@example.com, rather than only
checking that it was called. Add the same argument assertion to the related
action test.

Build the magic-link URL only from a configured or trusted origin.
The emailed magic-link URL uses the origin derived from the incoming request. When trustedProxyHeaders is off and no baseURL or BASE_URL is set, getOriginURL adds the request's own origin to the trusted list before checking it. Any request host therefore passes, and the bearer token is emailed to a link on that host. Use the configured base URL, or require the origin to match trustedOrigins. Reject the request when neither is configured.

Add coverage for the remaining magic-link verification branches.
The current tests cover only a missing token and a wrong token type. Add cases for expiration, revoked tokens, revokeToken returning false, inactive users, and user.email !== identifier. When revokeToken returns false, assert that createSession is not called.
Add a concurrent redemption test that sends two requests for the same token and asserts that exactly one succeeds.
Use a raw token value that differs from magicLinkTokenEntity.id. This makes the revokeToken argument assertion detect an incorrect token value.

- Around line 162-166: Add a breaking-change entry to the core changelog
documenting that the public CredentialsConfigContext helpers deriveSecret and
verifySecret return Awaitable values, which may be synchronous and can affect
consumers that call .then() directly. Keep the widened helper types unchanged.

- Around line 73-91: Update the account-related error handling in the send magic
link flow so unknown-user and inactive-user errors return the same response body
and redirect behavior as a successful request, without exposing account status.
Preserve the existing error responses for unrelated failures, and update the

Description
This pull request adds passwordless magic-link authentication to the stateful strategy. Applications can email users a verification link and establish a session when they verify its token.
Key Changes
sendMagicLinkandverifyMagicLinkAPIs and register thePOST /signIn/magicLinkandGET /signIn/magicLink/verifyendpoints.magicLinksconfiguration for token expiry, sign-up permission, and the email callback. Tokens expire after 30 minutes by default.Usage
Configure the email callback, then call the programmatic API:
Configure the email callback to send the provided verification URL:
Then request a magic link through the API:
The verification URL is sent to the user. Visiting it verifies the token and establishes a session.
