From the auth /security-review (contained fixes; architectural SA3 proxy-trust +
SA4 session-revocation deferred to the user):
- SB1: encrypt the OAuth access_token at rest (was plaintext while refresh_token
was encrypted) — a ~1h Google bearer credential. New security.decrypt_optional()
falls back to a refresh for legacy plaintext tokens; column is unbounded String.
E2E-verified: token refreshed → stored as Fernet ciphertext → 319-subscription
YouTube sync succeeded.
- SA5: password_login is no longer a timing/enumeration oracle — it always runs
argon2 (against a decoy hash for unknown/passwordless emails), so response time
can't reveal whether an account exists.
- SB2: Google login only ADOPTS+activates a pre-existing password account when
Google actually attests email_verified (defense-in-depth against takeover); and
the email sync won't overwrite with a value another account owns (avoids a 500).
- demo_login clears the wallet first (demo can't switch to / act as a real account
via the multi-account header); switch_account rejects a suspended target (which
would otherwise clear the whole session on the next request).
Re-review clean; ruff clean; localdev boots; YouTube auth path E2E-verified.
- app/utils.py: shared valid_email() + now_utc() (one email regex, was duplicated
in auth.py and admin.py with a looser "@"-in check elsewhere).
- security.hash_token(): one SHA-256 token hasher (was duplicated in auth.py + state.py).
- auth.admin_user dependency + count_admins() helper, replacing the inline role
checks and the last-admin count query repeated across admin.py/me.py/tags.py.
Add email+password auth alongside Google: argon2id hashing; users gains
password_hash/email_verified/is_active and google_sub becomes nullable (migration
0022); a single-use, hashed auth_tokens table for email verification + password
reset. Registration creates a pending (inactive, unverified) account + an access
request; sign-in needs verified email AND admin approval. Anti-enumeration: uniform
register/login/reset responses (a correct-password owner still gets a specific
pending reason). allow_registration flag (DB-tunable). Admin users-list + role
endpoint (guards: not self, not demo, not the last admin); approving access (or a
manual whitelist add) now activates the matching pending account. current_user
rejects deactivated accounts. Verified end-to-end via curl + DB.
- docker-compose with Postgres 16 + slim Python API image
- FastAPI app with session middleware, health endpoint, static login page
- Google OAuth (Authlib) with email invite-list whitelist; admin role support
- User + OAuthToken models; refresh tokens encrypted at rest (Fernet)
- Alembic migrations, run automatically on container startup
- Postgres backup/restore scripts for portability between machines
