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, .nt2backup 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 |
Enable optional category packs (Crypto, Bank, Document, and more) in Settings. Every vault includes core Credential and Secure Note templates.
Share with another person
Inbox, trusted contacts, and Receive/Send sharing are available in the app. Local storage and .nt2backup backup work offline with no subscription.
API keys to a contractor
Yuki keeps production API keys in Credential items—not in Slack. 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. Hand off a .nt2share file or encrypted link instead of LINE photos; safe presentation can 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. 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. Safe presentation with masked fields on his phone; nothing uploaded.
Available now for handoff: vault-to-vault exchange, encrypted links, .nt2share files, and full-vault .nt2backup export (trusted migration only).
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 (.nt2backup) | Whole-vault migration | Never |
Pending shares appear in your Inbox until you accept or decline. Open Receive/Send hubs at https://se.nt2.me/receive/{tab} and https://se.nt2.me/send/{tab}.
Availability
Available now: core Credential + Secure Note templates, optional category packs, encrypted attachments, clipboard auto-clear, .nt2backup export/import, multiple vaults on one device, trusted contacts, Inbox, vault-to-vault send, encrypted links, .nt2share files, and safe presentation mode.
Pick a category first
