Encrypt a password, API key, or note in your browser and get a one-time link that self-destructs after it is viewed.
Zero-knowledge. Your secret is encrypted on this device before it is sent. The key lives only in the link (after the #) and is never transmitted to the server — so this server literally cannot read your secret.

Your one-time link is ready
Copy it now and send it to the recipient. Anyone with this exact link (including the part after #) can view the secret once. We cannot show it to you again.
The QR code carries the whole link, key included. Let the recipient scan it
on their own device, then close this page.
Send each person their own link. Each one works on its own (its own key, its own views), and Secrets shows whose has been opened. We cannot show these links to you again.
