When we store files in the cloud service like Dropbox, one of our most concerns might be “is Dropbox secure”. Yes, the Dropbox is quite safe to use since files are encrypted using 256-bit Advanced Encryption Standard (AES).

Overview of Dropbox Security Features

As a matter of fact, Dropbox is designed with multiple layers of protection to keep your files secure, above and beyond the 256-bit Advanced Encryption Standard. These layers of protection include:


Dropbox uses Secure Sockets Layer (SSL)/Transport Layer Security (TLS) to protect data when users transfer data between Dropbox apps  (currently desktop, mobile, API, or web) and our servers. SSL/TSL creates a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption. Similarly, data in transit between a Paper client (mobile, API, or web) and the hosted services is encrypted via SSL/TLS.

Two-step verification

With two-step verification, you'll need both your password and your phone to gain access to your Dropbox. Any time you try to sign in from a new device, you’ll be required to input a unique six-digit code that will be received via text message or through a mobile app. So, you’ll have to enter both your password and this code before you can access your Dropbox. It provides 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 an authenticator app

Regular Test

Dropbox regularly test their applications and infrastructure for vulnerabilities and apply hardening measures to enhance security and protect against potential attacks. This includes employing encryption, access controls, and other security practices to safeguard user data.

File Permission

Only those who have gotten the link to the files can view the public files.


Bonus Tips to Protect Your Dropbox Files

The following methods are not only for enhancing the file security in Dropbox, but also other cloud drives.

Set strong passwords and enable two-factor  authentication

To ensure the security of Dropbox files, the first step is to set a strong password, which should contain letters, numbers, and special characters, and be at least eight digits long, rather than only simple numbers. In addition, do not use easy-to-guess passwords, such as personal information such as birthdays, mobile phone numbers, etc. Besides setting strong password, you can also enable two-factor authentics.

Protect your online privacy and avoid social attacks

In order to prevent social attacks, users should not open email attachments, click on suspicious links, but also be vigilant, and not easily trust information of unfamiliar people or institutions. Thus, users can reduce the risk of being hacked, and thus protect their private files.

Regularly backup

Regularly backing up your files is one of the important ways to protect the security of your personal files. You can backup important files to external storage devices or other cloud storage accounts to prevent file loss or damage.

If you need to backup to another cloud storage, you can use MultCloud, which is an online multi-cloud management tool that allows you to easily transfer, sync, and backup cloud storage data.

  • Offline Backup: Don't rely on network connection, but use the data traffic for backing up cloud files.
  • Direct Backup: Don't go through the local storage, but directly backup files across different clouds online.
  • Auto Backup: Back up data regularlywithout having to manually initiate each backup
  • Cross-Platform Access: Access your cloud files from devices or operating systems.

Encrypt important files

Additionally, encryption is crucial for protecting the security of your personal files. You can use encryption software to encrypt important files, ensuring that only authorized individuals can decrypt and view the file contents. By regularly backing up and encrypting important files, you can prevent file loss, leakage, and ransomware attacks, thereby better protecting the security of your personal files.

Use reliable antivirus software

Last but not least, in the process of using the web drive, the user should also install and update the anti-virus software in a timely manner.


So, Dropbox indeed takes many security measure to keep their users’ files safe in the cloud storage. To add an extra protection to your vital data, you can also set strong and complex password, back up Dropbox files regularly, install reliable anti-virus software, etc.
