Two-step verification is an important security measure that can help protect your Dropbox account from unauthorized access. By enabling two-step verification, you can add an extra layer of security to your account by requiring a unique code to be entered in addition to your password when logging in. This code is sent to your mobile device or email address, making it much harder for someone to gain access to your account without your permission.
