once

Share a secret through a link that works once.

Your browser encrypts it before it's sent. The recipient opens it once, then it's deleted.

Kept only in this browser, to recognise the link below.

The recipient needs it as well as the link. Send it another way, like a phone call.

How it works

  1. Your browser encrypts the secret with a new random key. Only the scrambled version is sent here.
  2. The key goes in the link after the #. Browsers never send that part to a server, so we can't read your secret.
  3. When the recipient opens it, the scrambled copy is deleted, and the link stops working. Unopened links are deleted when they expire.
