How do I send a file?


To send a file securely using Lockdrop, click on the Browse dialog box and select the file from your device. Alternatively, you can drag-and-drop a file from your device into the Lockdrop website.


You have the option to specify how long a file is able to be retrieved by the recipient. When this expiration period ends the encrypted file is completely removed from our systems and is unrecoverable. We recommend advising the recipient to save the file after retrieiving it!

If you don't specify an expiration and you're signed in, the default is 7 days.


Based on the contents of the file you're sending you may be required to ensure it does not leave certain geographical boundaries. By specifying a country you can ensure the encrypted document is stored temporarily on systems within a certain geographical region.

If you don't specify a country and you're signed in, the default is United States.


You have the option of adding recipient verification functionality to the file you're sending. We recommend you use this functionality when you want to ensure the recipient is the only one who can retrieive it. There are two options to achieve this:


The SMS option is the most convient option, however it does require you to know a mobile phone number of the recipient of the document. The way this works:

  1. Specify the recipient's mobile phone number.
  2. Send the generated link to the recipient.
  3. Recipient opens the link.
  4. A one-time passcode is sent the recipient's mobile phone when retrieving the file.


Alternatively, if you don't have the recipients mobile phone number, you can use the passphrase.

  1. Specify a passphrase.
  2. Send the generated link to the recipient.
  3. Send the passphrase to the recipient through a secondary means (ex. phone call).
  4. Recipient opens the link.
  5. Recipient enters the passphrase when retrieving the file.

We highly recommend sharing the passphrase through a different medium than the way you share the link! For example, send the generated link in an email and the passphrase in a phone call.

For any additional questons feel free to contact us!.
