Web sessions were stateless JWTs with no server-side store: the revocation
hooks in session.service were stubs that only logged. As a result web logout
was client-side only (a copied cookie stayed valid until natural JWT expiry)
and a password change never invalidated existing sessions. The mobile bearer
flow already had revocable, DB-stored tokens; this brings the web/cookie flow
to parity.
Two-layer revocation, both enforced in requireAuth (which already loads the
fresh user row each request):
- Per-session denylist: new `revoked_sessions` table keyed on the JWT `jti`
(already minted per session). A single logout adds this session's jti;
rows self-expire at the token's own exp and are pruned on boot. New model
`revokedSessions` mirrors the `mobileSessions` db/model split.
- Per-user cutoff: new `users.tokens_valid_after` column. A password change
(and the new `invalidateSessions` helper) bumps it to NOW(); any token whose
iat is at or before the cutoff is rejected. The comparison is inclusive so a
token minted in the same wall-clock second as the change is still revoked.
Wiring:
- session.service: revokeSession / invalidateSession / invalidateAllUserSessions
now delegate to the stores; sessions carry `expiresAt` (JWT exp) so logout can
set a self-pruning denylist row.
- /logout gains best-effort attachSession so the controller can revoke this
session's jti and log auth.logout; stays a no-op for anonymous callers.
- users.model.update bumps the cutoff whenever the password hash is rotated.
- schema.sql: revoked_sessions table + tokens_valid_after column, added to the
CREATE and to the idempotent migration block (ensureSchema on boot).
Verified end-to-end against the local dev DB: a captured cookie is rejected
after logout, and an existing session is rejected after a password change while
re-login with the new password succeeds. Full server test suite green (96).

Refactor authentication into a provider-agnostic session layer and build
two new auth surfaces on top of it, without changing local password/TOTP
behavior. Every flow now issues sessions through
sessionService.createSession(user, authMethod).
Part 1 — Session abstraction (backward-compatible refactor):
- New server/src/auth/: token.js (JWT/cookie primitives), session.service.js
(create/validate/partial-TOTP/revoke), session.middleware.js
(attachSession/requireAuth/requireRole). utils/auth.js is now a thin
compat facade so existing imports are unchanged.
Part 2 — Mobile bearer auth (additive):
- /api/v1/auth/mobile/{login,refresh,logout}: short-lived access JWT +
long-lived refresh token, stored hashed and rotated on use, in a new
mobile_refresh_tokens table. Reuses web bot-scoring/backoff; single-request
TOTP. token.signToken gains a backward-compatible expiresIn option.
Part 3 — Pluggable SSO (Google, Discord, generic OIDC):
- OAuth2Provider base + built-in Google/Discord (fixed endpoints) + generic
OIDC, a registry with health/validation, PKCE+CSRF transaction state, and
discovery (GET /auth/providers), start/link/callback routes.
- Link-only policy: SSO signs in only to an already-linked account; external
identities are never auto-provisioned. Client secrets encrypted at rest
(AES-256-GCM, utils/secretBox.js). Admin CRUD (/admin/auth/providers) and
account linking (/admin/account/identities). New auth_providers +
user_identities tables.
Frontend:
- Login page renders provider buttons from /auth/providers (inline SVG icons,
graceful with zero providers). New Authentication admin view
(Local/Google/Discord/Custom). Account page linked-accounts section.
Tests: 83 passing (session, mobile, providers, registry, secretBox, ssoState,
ssoCallback) — all DB-free via fetch mocks + model stubs. README + .env.example
updated.
