One-time secret link
Send a password, a key or a small file through a link that opens once and then destroys itself. It is encrypted in your browser, so we cannot read it.
How does it work?
- Type the secret, or attach a file, and choose how long the link may wait.
- Copy the link and send it to the one person who needs it.
- They press Reveal. The secret is shown to them and deleted from our server in the same step.
- If they never open it, it is deleted when the time runs out. You can also destroy it yourself while this page is open.
Can you read what I send?
No. The secret is encrypted in your browser before it leaves, with a key that exists only in the link. The key sits after the “#”, which browsers never send to a server, so we store text we cannot read. That also means we cannot recover a secret for you, and cannot see what anyone sends.
What if a chat app previews the link?
Opening the page does not use the secret up. It is released only when someone presses Reveal, so the previews that messaging apps make do not destroy it.
What it does not protect against
Whoever opens the link first reads the secret, so send it only to the person it is for, and send it on a different channel from the username or account it belongs to. If the link says it has already been opened and it was not you, treat the password as known and change it. After someone reveals a secret they can copy it; this tool controls the trip, not what the reader does next.
