Sharing passwords
Server logins, Wi-Fi codes, onboarding details — read once, gone.
Say it once — and never again.
OTN turns a message into a one-time link. End-to-end encrypted, no account, auto-deleted. No history, no archive.

What people use OTN for
Sensitive paperwork
IBANs, tax IDs, signed authorisations — keep them out of long email threads.
Personal things
Secret notes, gift ideas, short confessions. If it should disappear, it does.
How it works
01
Write
Type your message. It is encrypted in your browser before it reaches the server.
02
Share
You get a one-time link. Send it by mail, chat, or QR code.
03
Vanish
After it is read or expires, the note is permanently deleted.
How secure is this?
Your message is encrypted with AES-256-GCM right in your browser. The key lives in the link's fragment (#) — and is never sent to the server.
We cannot read the content of your notes. Even if our servers were compromised, the stored notes would be useless.
AES-256 encrypted
