Offline vault guide
Last updated: 1 Jun 2026
NT² is offline by default, not offline as a fallback. Your encrypted vault lives on your device first; the network is optional.
Do I need internet to use NT² Vault?
No, after the first load of se.nt2.me. Create, unlock, search, edit, attach files, and export .nt2vault backups without any network connection.
How is NT² different from "offline mode" in cloud vaults?
Many password managers require an account and sync metadata from the cloud; offline mode is a degraded cache. NT² stores the authoritative vault in local SQLite + IndexedDB on your device—no account required to start.
What works offline vs what needs the network?
Offline: all local CRUD, attachments, export/import, password generator. Network (optional Premium): cross-device sync, cloud attachment storage, share relay delivery.
Can I install NT² for offline access on mobile?
Yes. Add se.nt2.me to your home screen (PWA). Native iOS, Android, and desktop shells are on the roadmap with the same vault model.
Local-first architecture
Your browser
├── SQLite (wa-sqlite → IndexedDB) ← encrypted asset rows
├── BlobStore (IndexedDB) ← encrypted attachment ciphertext
└── In-memory vault key ← cleared on lock / idle timeout
Cloud sync (Premium) is a blind replica of ciphertext—you opt in from Settings. The free tier never requires it.
When offline matters
| Scenario | Why local-first helps |
|---|---|
| Travel / spotty Wi‑Fi | Full vault at embassy, airport, or remote site |
| Distrust of cloud | No vendor can read what they never receive |
| Quick copy | Open vault, copy IBAN or routing number, clipboard auto-clears |
| Power outage | No sync server dependency for read access |
Getting started offline
- Visit se.nt2.me once while online to load the app shell.
- Create a vault with a strong master password.
- Add your assets—bank, crypto, documents, credentials.
- Export a
.nt2vaultbackup before switching devices.
See Getting started for browser support and master password basics.
