Dropbox uses multi-factor authentication to add an extra layer of security to your account. With this feature turned on, you’ll need a six-digit security code as well as your username and password to sign into your account. You’d also need this code to link a new computer, phone, or tablet. You can have the codes sent to your phone in text messages or generated by a mobile app like Google Authenticator or Duo Mobile.
Dropbox also offers the option of using a security key, rather than six-digit codes, for two-step verification. Security keys offer extra protection against phishing attacks and are convenient to use.
Sign in to dropbox.com.
Click your avatar.
Select the Security tab.
Toggle Two-step verification to On.
- If you see Managed by single sign-on under the Security tab, your team uses single sign-on (SSO). This means you might not be able to use two-step verification with Dropbox. Contact your admin to learn more.
Click Get started.
Re-enter your password.
Enter a security code to complete the setup (you'll receive it either via text message or authenticator app, depending on the preferred method you entered).
Note: If you use an authenticator app to receive your verification codes, please add primary and secondary backup phone numbers.
