By default, all your drops are linked with a short, easy to remember short link. However, because the links are so short, it can be somewhat easier for someone to guess them and stumble across one of your drops.
With a Pro subscription, Droplr gives you the option of using longer, harder to guess URLs. These links provide a small additional layer of privacy.
After converting a drop to "private", when someone visits the
http://d.pr/code URL, they'll be presented
with a password input box before they can view the drop. This
allows you to send out the link to a drop with one method and send
the password separately for added security.
However, you can bypass this and link to private drops by
including the password in the URL. For example, you can send
someone the link
http://d.pr/code/password. The usual
features of drops still work as well, e.g.,
http://d.pr/code/password+ will link to the direct
file so that you can embed it on other websites.
We still do not advocate storing sensitive information with Droplr, as it's still theoretically possible for someone to access your drops (however unlikely). But with a Pro subscription it's now easy to add a little more privacy to your uploads while still retaining the convenience of Droplr's service.
