Short examples for storing on your device and sharing with another person—without email attachments or chat screenshots.
NT² helps you store structured secrets locally and share them when someone else needs a copy. Below: four store patterns, four share scenarios, and what is available today.

Store on your device (available now)
No account required. Works offline after the first app load.
| Category | Example | What NT² gives you |
|---|---|---|
| Crypto | Record a hardware-wallet mnemonic | Masked fields, lock on idle, .nt2vault backup—not a photo in your camera roll |
| Bank | Monthly rent IBAN to a Berlin landlord | One Bank item; copy IBAN; clipboard clears in 30 seconds |
| Document | Passport renewal abroad | Metadata + encrypted front/back scans in one item; open offline at the embassy |
| Credential | Stripe / GitHub API keys after a leak | Labeled items, password generator, copy once and lock |
Share with another person
Sharing in the app is still being built (Inbox, trusted contacts, send flows). Local storage and .nt2vault backup work today. Until sharing ships, do not paste secrets in Slack or messaging apps—see Security guidelines.
API keys to a contractor
Yuki keeps production API keys in Credential items—not in Slack. Coming soon: send one item via encrypted link (separate share passphrase + expiry) or vault-to-vault (contractor accepts in Inbox). Share passphrase is never your master password.
ID front and back to a landlord
Ana stores national-ID scans as encrypted Document attachments. Coming soon: hand off a .nt2share file or encrypted link instead of LINE photos; optional safe presentation to show only issuer and partial number in person.
Bank details to family
Amara shares one Bank item with her brother’s vault—routing and account only, not her whole vault. Coming soon: vault-to-vault send; he accepts or declines in Inbox.
Proof in person, nothing extra exposed
Luis needs employer name and last-four digits for a mortgage meeting—not a full PDF statement. Coming soon: safe presentation with masked fields on his phone; nothing uploaded.
Available now for handoff: export a full vault with .nt2vault (trusted migration only—not for casual API-key paste).
Ways to share
| Way | Best for | NT² sees plaintext? |
|---|---|---|
| Vault to vault | Family, partner, recurring trust | Never |
| Encrypted link | Contractor, lawyer, one-time | Never |
Share file (.nt2share) | AirDrop, USB, email attachment | Never |
| Safe presentation | In-person or video verification | Never (stays on your device) |
Full backup (.nt2vault) | Whole-vault migration | Never |
Pending shares appear in your Inbox until you accept or decline.
Availability
Available now: four templates, encrypted attachments, clipboard auto-clear, .nt2vault export/import, multiple vaults on one device.
In progress: trusted contacts, Inbox (receive via QR or link).
Coming soon: vault-to-vault send, encrypted links, .nt2share files, safe presentation.
