How to send a secret that opens only once

A 38-second animation: write a secret, such as a temporary password, as a LOCK.PUB one-time secret, set a password, and send the link with the password separately. The first successful unlock shows it; after that the same link won't open it again. The page has a copy button and can't stop screenshots, so send it only to someone you trust.

Need to send a password just once?

Passwords in chats get copied everywhere.

There's another way.

Make a one-time secret on LOCK.PUB…

…and set a password.

Send them the link…

…and the password, separately.

With the password, it opens once.

After that, the link won't open it again.

They can still copy it…

…so send it only to someone you trust.

Someone with only the link?

No password, no secret.

One secret, one reveal.
