Beyond Link Locking: The Complete Guide to LOCK.PUB's 7 Secret Content Types

You might know LOCK.PUB as a tool for putting passwords on links. But there is so much more you can do. Beyond URL locking, LOCK.PUB offers 6 other powerful content types -- all protected by passwords.

This guide walks you through every content type LOCK.PUB supports.

All 7 Content Types at a Glance

🔗 URL Lock -- Put a Password on Any Link

The most well-known feature. Set a password on any URL, and only people who know the password can access it.

When to use it:

  • Sharing premium content links with specific people only
  • Sending internal document links externally with an extra layer of authentication
  • Double-protecting Google Drive, Notion, or other shared links
Recommended settings:
- Password: Simple but unpredictable combination
- Expiration: 1 day to 7 days as needed

📝 Secret Memo -- Password-Protected Text

Safely share passwords, API keys, secret messages, and other sensitive text. Instead of sending passwords directly through a messenger, wrap them in a secret memo.

When to use it:

  • Sharing server passwords or API keys with teammates
  • Giving Wi-Fi passwords to guests
  • Sending secret messages or surprise party details
Recommended settings:
- Password: A strong password
- Expiration: 1 hour to 24 hours
- Access limit: 1 view (Pro) -> auto-deletes after reading

💬 Encrypted Chat -- Anonymous E2E Encrypted Chat Room

An anonymous chat room that only people with the password can join. Every message is end-to-end encrypted, meaning even the server cannot read the content.

When to use it:

  • Whistleblowing or anonymous reporting
  • Collecting anonymous feedback
  • Temporary team discussions
  • Corporate audit channels
Recommended settings:
- Password: A password known only to participants
- Expiration: Delete after the meeting ends (Pro)

  • Running anonymous satisfaction surveys
  • Holding yes/no votes on sensitive matters

🖼️ Secret Image -- Password-Protect Your Photos

Share sensitive images like IDs, contracts, and design mockups with password protection. Unlike messengers that auto-save photos to the gallery, secret images become inaccessible after expiration.

When to use it:

  • Safely sending ID or passport photos
  • Showing design previews to clients
  • Sharing medical record images

🎨 Secret Board -- A Shared Secret Canvas

A password-protected collaborative drawing board. Draw together in real time or express ideas visually.
