Local-first
Your vault runs on your device. Create, search, and edit assets offline—no account required to start.
Null Trust²
Your structured vault.
Offline by default.
A zero-knowledge vault for the data that matters most—bank accounts, crypto keys, identity documents, and credentials. When someone else needs a copy, share it structured and encrypted—not as email attachments or chat screenshots.

Built for privacy, not passwords alone
Zero-knowledge
Your master password and keys never leave the browser. We cannot read your ciphertext.
Structured templates
Purpose-built fields for crypto wallets, bank accounts, documents, and credentials—not blank notes.
Structured categories
Fill-in-the-field templates with copy buttons and encryption—not a freeform canvas.
- Crypto wallet Mnemonic, keys, notes
- Bank account Account and routing numbers
- Document IDs, scans, attachments
- Credential Usernames, passwords, API keys, URLs
Share with people—not with the cloud
NT² is built for the moment your data must reach another person: a contractor, landlord, family member, or your own second device. You choose what leaves the vault; recipients decrypt with their vault or a share passphrase—NT² never sees plaintext.
API keys & service credentials
Hand production API keys or admin logins to a teammate in structured Credential fields—via encrypted vault exchange or a passphrase-protected link instead of Slack or email.
ID front & back scans
Store national ID or passport images as encrypted Document attachments, then share one package with a landlord or employer—not loose photos in a messaging app.
Bank details to family
Send routing and account fields to another NT² vault or a one-time encrypted link when setting up joint finances—without screenshotting your banking app.
Show only what's needed
Present redacted fields in person or on a call (e.g. confirm issuer without exposing full document numbers)—see [Safe presentation](/guides/safe-presentation).
How sharing works
- Vault to vault Encrypted exchange with another NT² user; accept or decline in your Inbox
- Encrypted link Passphrase + link for someone without NT²
- Share file Offline `.nt2share` handoff (AirDrop, USB, email attachment)
- Safe presentation Redacted view for in-person verification
Inbox, trusted contacts, and Receive/Send sharing are available in the app today. Local storage and `.nt2backup` backup work offline with no subscription.
Who NT² is for
Structured fields for the assets people still store in notes apps, screenshots, and email drafts.
Crypto holder
Record mnemonics in a Crypto template—not a photo in your camera roll or a draft email.
Expat / traveler
Keep passport details and encrypted scans in one Document entry—ready offline at the embassy.
Privacy maximalist
No account required to start. Export a `.nt2backup` backup and move devices without trusting the cloud.
How NT² differs
We do not compete on browser autofill—we focus on structured storage, person-to-person encrypted handoff, and true offline use.
| NT² Vault | Typical password manager | |
|---|---|---|
| Primary focus | Financial & identity assets + sharing | Login credentials & autofill |
| Hand off to another person | Encrypted vault, link, or file | Email, chat, cloud folder |
| Default storage | Local SQLite on device (OPFS) | Cloud-synced |
| Offline | Full vault by default | Limited without sync |
| Premium sync | $2.99/mo | Varies |
Common questions
Does my master password ever leave my browser?
No. Your master password is used only inside the browser's Web Crypto API to derive encryption keys. It is never sent to NT² servers.
Can NT² recover my vault if I forget my password?
No—and that is intentional. Without your master password or a valid `.nt2backup` backup, ciphertext cannot be decrypted. NT² has no back door.
Do I need an account to use NT² Vault?
No. Create a vault entirely on your device without email signup. Cloud features (Premium sync) use a Vault Key DID—not your email.
Can I use NT² Vault offline?
Yes. After the first load, core vault operations work fully offline. Your encrypted data lives in local SQLite on device (OPFS) with attachment ciphertext in a per-vault BlobStore.
Does the vault app support other languages?
Yes. The vault app at https://se.nt2.me supports eight interface languages in Settings (English, Japanese, German, French, Spanish, Korean, Traditional Chinese, and Simplified Chinese). This marketing site is available in English and Traditional Chinese.
Simple pricing
Full local vault free forever. Premium sync when you need multiple devices.
