If you’re one of those people with the password “password”, this next bit isn’t for you. But if you do worry about your online security--maybe you’ll be interested. According to The Verge, Dropbox is introducing two-step authenication.
You'll need to download the latest beta version of the desktop software to try the feature out. Once you do, visit this link to activate yourself in the beta, and follow the steps to turn on two-step authentication. Just like Google's popular version of the security feature, you receive the codes via text message or an authenticator app that uses Time-based One-Time Password (TOTP) protocol (e.g. Google Authenticator).
