Password-protected access
Recipients must unlock the link with the password you set before protected content is shown or delivered.
Security & trust
Share secrets with controls people can understand
LOCK.PUB helps you create password-protected links for URLs, memos, files, images, audio, chats, and secure requests. Use expiration, access limits, and read receipts to keep private sharing out of inboxes and chat history.

How LOCK.PUB protects a private share
Expiration and access limits
Set when a link starts, when it expires, and how many times it can be opened before access stops.
Secure file and media delivery
Files, images, and audio are opened through verification routes instead of public storage URLs.
Read receipts
Pro read receipts show whether a link was opened, with time, device, browser, country, and referrer details when available.
What you can protect
Use one security model across the private things people actually need to send: links, notes, media, conversations, and intake requests.
Secret links
Password-protect a URL and add expiration or access limits before sharing.
Private memos
Share a note behind a password instead of leaving it in email or chat history.
Files and documents
Send private files through a protected LOCK.PUB link with controlled access.
Images and audio
Protect scans, screenshots, voice notes, and audio files with the same unlock flow.
Chats, boards, polls, and asks
Create private interactive spaces that require the password before entry.
Secure request links
Collect memos, files, images, and audio from others while keeping submissions visible to the creator.
Security controls before you share
These controls turn a normal private link into an expiring, limited, and easier-to-trust share.
Start time
Keep the link locked until the moment you choose.
Expiration time
Stop access automatically after the selected time.
Access limit
Use a one-time secret link or allow only a small number of opens.
Custom URL
Use a recognizable short path so recipients can spot the right link.
Pro adds proof and stronger control
Upgrade when you need read receipts, custom URLs, expiration controls, access limits, editing, deletion, and deeper dashboard history for client work or sensitive sharing.
Upgrade for read receiptsA clear privacy boundary
LOCK.PUB is designed for safer sharing, but recipients can still copy or save what they are allowed to open. Use strong passwords, share them through a separate channel, and avoid sending regulated or high-risk data unless your own compliance process allows it.
Security FAQ
Is this a one-time secret link?
It can be used that way when you set the access limit to one. You can also choose a longer expiration window or allow more opens when the situation needs it.
Can I see whether it was opened?
Basic open counts are available in the dashboard. Pro read receipts add timing, device, browser, country, and referrer details when available.
Are files and media protected?
No. They are delivered through password verification and protected routes rather than being exposed as ordinary public storage links.
How should I share the password?
For sensitive content, send the LOCK.PUB link and password through separate channels. That keeps a copied chat or email thread from containing everything needed to open the secret.
