After the recent security breach  experienced by some users of cloud storage service Dropbox , the company has announced that it is beginning to introduce two-factor authentication in an effort to improve cloud security. This means that users will have one extra step in the login process, but Dropbox hopes this change will mean keeping data stored in the cloud safe from cyber attacks.
The new system is optional, and fairly similar to Google’s new two-factor authentication method. Users will have the option to add their mobile devices to a whitelist and authenticate them to access their account. Then users can receive unique access codes via text or mobile app that supports the Time-Based One-Time Password system.
Examples of apps that can be used for two-factor verification include Google Authenticator, which works with iPhone, Android, and Blackberry smartphones; Amazon AWS MFA for Android; and Authenticator for Windows Phone 7. Upon entering their password and the authentication code they received, Dropbox users can then obtain access to their account.
Dropbox is a popular cloud storage service used by millions of individuals and business professionals. Since Dropbox users often store sensitive types of files or data in the app, such as passwords, financial data, and other business or personal information, the company vowed to improve security  measures after company officials learned of the attack.
For business users, this security measure might be worth the extra step so as to protect sensitive company data.
Dropbox has also announced a few other security measures since the breach, including automated mechanisms to help identify suspicious activity, a new page that lets users see all active logins on their account, and more vigilant measures regarding passwords and other secure data.
Users with the latest beta version of Dropbox have the option to switch on the two-factor authentication if they so choose. The new feature  will become available to all users in the coming weeks.
