"If someone forwards your shared link, can unauthorized third parties access your files? Passcode locks guarantee only your intended recipient can download."

Why Password Protection is Necessary for Shared Links

Open share links can be forwarded to unintended recipients:

Email Forwarding Breaches

Recipients forward emails containing open links to third-party vendors.

URL Leaks in Chat Channels

Links posted in Slack or Teams can be accessed by all channel members.

Unprotected Intellectual Property

Unreleased designs leaked to competitors via forwarded URLs.

1. Adding a Secret Passcode in 60 Seconds

Before generating your link, enable 'Passcode Protection' and type a secret key. Recipients must enter this passcode before file previews or downloads decrypt.

  • Client-side passcode validation before link decryption.
  • Prevents link forwarding access by unauthorized third parties.
  • Passcodes can be updated or changed anytime from dashboard.
