Native clients (Tauri/Android) authenticate sync with a long-lived device bearer token, alongside the existing web session cookie. Backend: - security.py: generate_token() (secrets.token_urlsafe) + hash_token() (SHA-256 — device tokens are already high-entropy, so no slow KDF; keeps per-request bearer auth cheap). Only the hash is stored. - device_tokens table (migration 0016): id, user_id, token_hash (unique), name, created_at, last_used_at. - login_required now accepts `Authorization: Bearer <token>` OR the session cookie. Session path stays DB-free (fast); bearer path looks up the token hash, sets g.user_id, and stamps last_used_at. - Endpoints: POST /api/auth/device-login (public; email+password → token, the native first-link flow), POST /api/auth/devices (session/bearer → token, web "link a device"), GET /api/auth/devices (list), DELETE /api/auth/devices/<id> (revoke). All owner-scoped; token shown once. Frontend: - Per-user (not admin) /account view "Linked devices": create a token (one-time reveal + copy), list devices (name, linked/last-synced), revoke with confirm. Top-bar device icon for all users; devices Pinia store. Tests (DB-free): token hash determinism + uniqueness; device endpoints auth-guard (401 without auth, before DB); device-login input validation.
