One-time secret: share a link that works once
Paste a password or private message and get a secret link. It's encrypted on your device, opens once, and then it's gone.

How the one-time secret link works
Paste your secret
Your browser encrypts it with a fresh key before anything is uploaded.
Send the link
The key rides in the link after the #, so only someone with the full link can unlock it.
Read once, then gone
The first open shows the secret and deletes it. Unopened secrets expire on their own.
One-time secret questions
What is a one-time secret?
It's a message that can be opened only once. You paste a secret, get a link, and send the link. The first time someone opens it, the secret is shown and then deleted, so the link can't be used again.
Can you read my secret?
No. Your secret is encrypted on your device before it's uploaded, and the key lives in the part of the link after the # sign, which browsers don't send to servers. We store scrambled text plus a one-way fingerprint of the key, which lets us refuse a wrong link without being able to unlock it.
What happens after it's read?
It's deleted from our database the moment the button is tapped. Opening the link again shows that the secret is gone.
What if nobody opens the link?
It deletes itself when the time you picked runs out: 1 hour, 1 day, 7 days or 30 days. The default is 1 day.
Is this a one-time password (OTP)?
Not exactly. A one-time password is a short code a site texts or emails you to log in. A one-time secret link is a way to send your own password or secret to someone so it can only be read once. Never put a login code someone texted you into any website they ask you to.
Will a link preview in WhatsApp, Slack or iMessage burn the secret?
No. The secret is only opened when a person taps “Read and destroy”, so chat app previews don't use it up.
What if the link gets cut off or mistyped?
Then we don't open it. The secret stays safe and unread until someone opens the full, correct link, or it expires.
Is it free? Do I need an account?
It's free and there's no signup. Paste, create the link, send it.
