When a one-time secret link helps

Use a one-time link for private text the recipient needs once, instead of leaving the secret itself in a searchable email or chat history.

Hand over a temporary credential

Move a recovery code, access phrase, or temporary password out of the conversation where you coordinate the handoff.

Send a single-use instruction

Share private directions that should be available for one successful viewing instead of remaining in a message thread.

Share with a recipient immediately

Create as a guest and send the link right away; the recipient only needs the link and the separately shared password.

One-time link or ordinary message?

A LOCK.PUB one-time secret separates the private text from the conversation and closes access after the first successful reveal.

One-time secret questions

What happens after the one-time secret is opened?

After the first successful password unlock reveals the note, LOCK.PUB blocks every later attempt to reveal it through that link.

Is the encrypted note deleted after it is read?

This tool promises one-time access, not deletion. LOCK.PUB blocks another reveal after the first successful access.

Do I need to sign up before creating one?

No. A guest can create one free one-time secret immediately. A Pro account supports repeated creation.

Does the recipient need a LOCK.PUB account?

No. The recipient only needs the link and its password. Send the password through a separate channel when the secret is sensitive.
