Usage guide
Prepare a note for one successful reveal
Move a recovery code, access phrase, or temporary password out of the conversation where you coordinate the handoff.
Keep the secret out of the public label
Put protected information in the private note field. Use a neutral public label, such as “Visitor instructions”, that does not reveal the contents.
Send the link and password separately
Set a password and share the generated link. Unlocking the actual delivery link yourself to test it can use its single reveal.
Let the recipient reveal the note once
After the correct password successfully reveals the note, it cannot be revealed again through the same link. Create a new link if you need to send it again.
What this tool protects
One-time access blocks later reveals through the link. It does not promise immediate deletion of every stored copy or prevent the recipient from copying or photographing the contents.
One-time secret tool
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.
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 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.
