In an effort to improve the security of its file-hosting service, Dropbox has introduced two-step verification.

This optional process requires members to submit a six-digit security code in addition to passwords upon signing in, or linking to a new computer, phone, or tablet.

The security code will be sent to your mobile phone via text message, or generated using a mobile authenticator app — ensuring that you’re the only person who’s able to access your account.

To enable two-step verification, visit the Dropbox security page (while you’re logged in) and look for the feature toward the bottom of the page. If you’ve already turned on two-step verification for Gmail, then this process will seem very familiar.

Last month, the company found that usernames and passwords stolen from other websites were used to sign in to a number of Dropbox accounts. Given the nature of the files being hosted, extra security is crucial.

Dropbox stated that it will be adding two-step verification for all accounts in the next few days. If you can’t wait, you can install the latest beta version and enable the feature now.
