On Monday night, news broke that hackers had reportedly obtained nearly 7 million Dropbox usernames and passwords. Dropbox says its service wasn’t hacked, but that the usernames and passwords had been stolen from various third-party services.
There are a ton of apps and services that integrate with Dropbox, making it nearly impossible to track down which ones have been compromised.
To play it safe, you should probably change your Dropbox password and enable two-step authentication if you haven’t already done so. The process takes less than five minutes, and is well worth it.
Two-step authentication is a method in which an app or service requests a separate means of authentication besides your password to log into your account. In most cases, this includes sending a text message with a code to your smartphone.
Now, it's time to enable two-factor authentication. In the 'Security' tab, select 'Enable' under 'Two-step verification.'
Choose how you want to receive your security code: either via text message or through a third party app.
Add a backup phone number (i.e. someone you trust like a spouse or roommate) in case you lose your phone and need to log in.
If all else fails, Dropbox provides you with an emergency backup code to disable two-step verification. Keep it in a safe place where no one else will see it.
