Overview

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. Since files are end-to-end encrypted, no one can view the files you send but your recipient, not even us!

For those who want to read more technical details you can do so here https://lockdoc.co/how-it-works

Things to note:
- No account required for recipients. They only need a passphrase to download the files. Upon entering the passphrase, the files are automatically decrypted and downloaded
- Log history of files you've sent via LockDoc link can be viewed in the dashboard (https://lockdoc.co/dashboard)
- Exceed Gmail file limit. There is no cap on how big the files you upload are, only the storage allotment of the plan you select

Pricing
