Can the other person share my secret further?

Once it is on their screen they can copy it, as with any message. What a one-time link prevents is the secret sitting in storage where a third party can find it later.

Does LinkPilot see the secret?

No. We receive ciphertext and never the key. Secrets created before 29 September 2026 were stored as plaintext until they expired; the security architecture page explains the model.

What if the secret is opened by the wrong person?

Your recipient will find a burned page and tell you. Treat the secret as exposed, change it where you can, and send a new link with a shorter expiry or, on Pro, a passphrase sent by a different route.

Is there a limit on how long the secret can be?

The creator takes ordinary text up to its size limit, which is enough for passwords, keys, notes and configuration blocks. Larger material goes as a file attachment from a free account.

Share a secret

Paste the secret, send the link, and the first view burns it.

How it works

01
Paste a password, a key, or a file

Encrypted in your browser before anything is sent. Burn after read is on for every anonymous secret.
02
Send the link

One URL. The key after the # stays in the browser and never reaches our servers.
03
The stored secret is gone

The first open burns the ciphertext. A second visit, by anyone, meets the destroyed page.

Browser-side encryption shipped on 29 September 2026. Secrets created before that date were stored as plaintext until they expired, and a file's name, size and type are still visible to us. Read the full security model.

How to share a secret without leaving a copy behind

Paste the text above and press the button. Your browser encrypts it with AES-GCM-256, keeps the key in the link after the #, and sends only ciphertext to LinkPilot. Send the link. The recipient opens it, presses reveal, reads the text, and the stored copy is destroyed in the same step. A secret shared this way exists in two places for a moment, your screen and theirs, and in no place after that.

Sharing secrets of every kind

The creator takes any text: a Wi-Fi password for a guest, a door code, a recovery phrase you are handing to a family member, an API key for a developer, a message you would rather not have quoted back in a year. For a key or a config file, a free account lets you attach the file itself, encrypted the same way.

A secret share expires unread after seven days; a free account lets you shorten that to one hour or 24 hours.
A free account can revoke a link from the dashboard before it is opened.
Pro adds a passphrase, a custom expiry and the audit timeline.

Why sharing a secret by chat or email is different

A message in Slack, WhatsApp or email is stored by the service, backed up, indexed and easy to forward, and it stays readable for as long as the account exists. A one-time link holds ciphertext that only the key in the link can open, and the first reveal makes every copy of the link useless. The thread still shows that something was sent; it no longer shows what.
