To set up two-factor authentication:
- Log in to dropbox.com.
- Click your avatar (profile picture or initials) in the bottom-left corner.
- Click Settings.
- Open the Security tab.
- Under Two-factor authentication, toggle to On.
Two-factor authentication adds an extra layer of security to your account. Once it's turned on, Dropbox will require both a six-digit code and your password whenever you sign in to Dropbox, or when you link a new computer, phone, or tablet.
