Is Dropbox safe to use?

At Dropbox, the security of your data is our highest priority. We have a dedicated security team using the best tools and engineering practices available to build and maintain Dropbox, and you can rest assured that we've implemented multiple levels of security to protect and back up your files.

You can also take advantage of two-step verification, a login authentication feature which you can enable to add another layer of security to your account.

Other Dropbox users can't see your files in Dropbox unless you share links to files or share folders. Like most online services, we have a small number of employees who must be able to access user data for the reasons stated in our privacy policy (e.g., when legally required to do so). But that's the rare exception, not the rule. We have strict policy and technical access controls that prohibit employee access except in these rare circumstances. In addition, we employ a number of physical and logical security measures to protect user information from unauthorized access.

  • SSL/TSL creates a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption
  • Dropbox applications and infrastructure are regularly tested for security vulnerabilities and hardened to enhance security and protect against attacks
  • Two-step verification is available for an extra layer of security at login
  • If you use two-step verification, you can choose to receive security codes by text message or from any Time-Based One-Time Password (TOTP) app, such as those listed here
  • Public files are only viewable by people who have a link to the file(s)

Dropbox is designed with multiple layers of protection, including secure data transfer, encryption, network configuration, and application- and user-level controls that are distributed across a scalable, secure infrastructure.

Access via third-party apps

Some third party apps with Dropbox integration will ask for permission to access your Dropbox. To grant access, you will need to log in to your Dropbox account and explicitly press the Authorize button when prompted. You can visit the Apps linked section of your account settings to review the apps you've granted permission to and revoke access at your discretion.
