Dropbox - 2 Factor Authentication Setup

Two factor authentication helps to protect a Dropbox account by adding an additional step when logging in from a new device.  The first step is the password on the account.  The second step is a login code on a physical device, usually a cell phone.

Even if an attacker gains access to the account’s password, they would also need your phone to successfully login.

These instructions demonstrate how to setup two factor authentication to use text messages or an authenticator app on a cell phone as the second factor of authentication.
