Send it once. Then it's gone.
A password, a key, a recovery code — the things you should never leave sitting in a chat history. Paste it here, send the link, and it deletes itself the moment it is read.
Opening a secret needs no account — only creating one does.

This secret is gone
It was opened once. There is nothing left on the server to show you.
What the second person to click the link would see.
How it works
Paste the secret
It is encrypted in your browser before it leaves it. The key never travels to the server.
Send the link
The key rides in the part of the URL browsers never send anywhere — so only whoever holds the link can read it.
It burns
Opened once, or expired, and the ciphertext is deleted. A second attempt finds nothing.
Why not just send it over chat
Read once, then nothing
A chat keeps your password forever, on every phone in the group and in every backup of it. This does not.
The server cannot read it
Encryption happens in the browser with AES-256-GCM. What is stored here is bytes nobody on this machine can turn back into text.
It expires anyway
Set a lifetime. If nobody opens it, it dies on its own instead of waiting around to be found.
You can tell it was read
Each secret shows whether it has been opened, which is how you notice when it was not you who opened it.
Nothing to sign up for
Whoever receives it installs nothing and creates no account. They click, they read, they are done.
On our own hardware
No third-party service in the middle of your credentials, and no company whose breach becomes your breach.
Stop pasting passwords into WhatsApp
It takes about as long, and afterwards there is nothing left behind to leak.
