Sharing overview
Last updated: 28 Jun 2026
Five handoff modes—NT² never sees plaintext.
Who this is for
Anyone who needs to hand structured secrets to another person—or show redacted fields in person—without email attachments, chat screenshots, or trusting NT² with plaintext.
What you need
| Tier | Free for all five modes |
| Vault state | Unlocked for Send and asset sharing; Receive and ?m= links can stash intent while locked |
| Network | Offline OK for vault-to-vault (local device), .nt2share, safe presentation, and .nt2backup; hosted encrypted links need network + cloud sync registration |
| Feature toggle | Optional Sent shares outbox (Settings → Features); Sound handoff tab on Receive when enabled |
Five sharing modes
| Mode | Best for | Leaves your vault? | NT² sees plaintext? |
|---|---|---|---|
| A — Vault-to-vault | Family, partner, trusted contacts | Encrypted envelope to recipient Inbox | Never |
| B — Encrypted link | Contractor, lawyer, one-time | URL + separate share passphrase | Never |
C — Share file (.nt2share) | AirDrop, USB, email attachment | Encrypted file + separate passphrase | Never |
| D — Safe presentation | In-person or video verification | Stays on your device—masked fields only | Never |
E — Full backup (.nt2backup) | Whole-vault migration you control | Entire encrypted vault snapshot | Never |
Modes A–D cover single assets or messages. Mode E is for trusted device migration only—not for sending one bank item to a landlord.
Hub routes and navigation
| Screen | Path | Notes |
|---|---|---|
| Receive (QR default) | https://se.nt2.me/receive | Tabs: /receive/link, /receive/file, /receive/sound |
| Send (text default) | https://se.nt2.me/send | File tab: /send/file |
| Contacts | https://se.nt2.me/contacts | Trusted vault address book by Key DID |
| Inbox | https://se.nt2.me/inbox | Accept or decline pending shares |
Receive and Send live in the app bar—not in the bottom nav. Inbox is where inbound vault-to-vault and link imports wait until you act.
Typical flows
Send one asset to a contact
- Open an asset → Share (or use Send for ad-hoc text/files).
- Choose Send to another vault, pick a contact, and deliver via link, QR, cloud relay, or nearby audio.
- Recipient reviews in Inbox → Accept or Decline.
One-time link to someone without a vault contact
- Share → Share link (or Send hub Text tab).
- Set expiry / burn-after-read if offered; copy URL and share passphrase separately.
- Recipient opens the link—often via Receive → Link—and imports to Inbox or a read-only view.
Show ID or bank details in a meeting
- Open the asset → Present (safe presentation).
- Toggle which fields are visible; use timed reveal for sensitive values.
- Nothing uploads—see Safe presentation.
Tips and common mistakes
- Share passphrase ≠ master password. Treat share passphrases like one-time codes; send them out-of-band (different app, in person, phone call).
?m=is for payloads addressed to you, not for browsing Settings. Normal paths likehttps://se.nt2.me/settingsdo not use?m=. Details: Sent to me.- Inbox is not automatic storage. Pending messages stay queued until you accept—nothing merges into Assets without your confirmation.
- Verify contacts before high-trust shares: confirm signing key fingerprints out-of-band.
- Do not
.nt2backupto untrusted parties—that file contains your whole vault ciphertext.
