Overview

Send & receive encrypted files in just a few clicks

Simple way to secure file attachments in Gmail. The first 3 secure links are free! When you're ready, sign up for the per-link or subscription plan at https://lockdoc.co/sign-up How it works: 📎 Click the blue "Upload" button in your Gmail compose window, and select files as normal 🔗 A download link for the encrypted files is inserted into the email body 📨 In order for recipients to download the files, they'll enter a passphrase. You choose how it is shared. You can copy it and share it yourself, or have LockDoc share the passphrase automatically with your recipient once your email is sent (via email or SMS) It's secure file sharing in just a few clicks.
