About LockDoc

Send secure file attachments from Gmail with end-to-end encryption. How it works: 1. Click the blue LockDoc upload button in Gmail and select your files. 2. Files are encrypted in your browser before upload. 3. A secure download link is inserted into your email. 4. Choose how to share the passphrase. AutoLink: Passphrase embedded in the secure link for simple recipient access. Copy Passphrase: Share the passphrase separately by SMS, phone, or another channel. Recipients do not need a LockDoc account. They only need the secure link and passphrase.
