Lost phones, or other issues with two-step verification

In order for two-step verification to work correctly, you'll need a mobile device capable of receiving text messages or running a compatible mobile authenticator app. You should disable or reset two-step verification by visiting the Security tab in Dropbox account settings. This will help if you're encountering any of the following issues:

  • You're not receiving text messages
  • You've lost your phone
  • Your mobile authenticator app isn't working

How to access your account settings

The easiest way to access your account settings is on a computer you've recently used to sign in to dropbox.com. If you haven't yet signed out, or if you previously selected the Trust this computer option when signing in, you should be able to go to dropbox.com in your browser. From there you can access your account settings without an additional security code.

Access account settings via the Dropbox desktop app

You can also access your settings through the Dropbox desktop application. If the application is running and linked to your account, click the Dropbox icon in your system tray (Windows) or menu bar (Mac) and then click the globe icon. This will take you straight to dropbox.com, where you'll be signed in automatically.

Access your account settings using an iOS device

If your account is still linked to your smartphone, you may be able to disable two-step verification from the Security page of the Dropbox mobile app:

  1. Open the Dropbox mobile app and tap Settings.
  2. Tap Link a Computer.
  3. Follow the instructions given.
  4. Once you've scanned the QR code, you will be automatically signed in to your Dropbox account.
    • Note: If you're not prompted for your two-step verification code then the application on your phone is not linked to your Dropbox, and you will not be able to sign in using this method.
  5. Click the Dropbox icon on the top left corner of the welcome page to access your Dropbox account. From here, you can disable two-step verification from the Security page.

Access account settings by sending a notification to the Dropbox mobile app

If you're signed in to the Dropbox app on an iOS or Android device, you can send a notification to that device. You can use this notification to complete the sign-in.

  1. Enter your username and password on the login page, and then click Sign in.
  2. Click Having trouble getting a code?
  3. Review the list of connected mobile devices, and click Send me a notification beside the name of the device you'd like to send the notification to.
  4. Open the notification on that device. Review the information to be sure the sign-in attempt is your own.
  5. Tap Yes on your mobile device. You should then be automatically signed in on whatever browser you were using to access Dropbox.

Access account settings using an emergency backup code

As a last resort, you can sign in using your password and the emergency backup codes given to you when you first turned on two-step verification. We also recommend changing your password if you've lost your phone.

  1. Enter your username and password on the login page, and then click Sign in.
  2. Click Having trouble getting a code?
  3. Click Enter emergency backup code.
  4. Enter one of your emergency backup codes, and then click Submit to sign in.


  • When entering a backup code, be careful to transcribe the code correctly. A "1" (one) can look like an "L," a "0" (zero) can look like an "O," and vice-versa. If you're unsure whether it's a letter or number, try different combinations of the backup code.
  • If you've used your last backup code, you will be prompted to generate new backup codes.

Restarting two-step verification if you disabled it

If you have a smartphone, you should re-enable two-step verification using an offline authenticator app. This is especially true if you encounter frequent problems receiving SMS text messages. Offline authenticator apps are available for Android, BlackBerry, iOS, and Windows phones.

Dropbox Business users

Your administrator can disable two-step verification for any member of the team. Admins can do this by going to the Members page of the Admin Console and selecting Disable two-step verification from the options menu for the member.

Also note that you may not be able to use two-step verification through Dropbox if your admin has turned on the single sign-on (SSO) feature. This feature lets users access Dropbox by using their company's sign-in page. Contact your admin to find out whether this feature has been turned on. If so, learn more about what you need to do to access Dropbox on the web, computers, and mobile devices.

Common issues with two-step verification

I set up two-step verification using an offline authenticator app

Please note that the security codes that an offline authenticator app generates are unique and time-sensitive. These codes are also dependent on the time and date to operate. To ensure that they work correctly, be sure that the time and date settings are correct on both your phone and the computer you are attempting to sign in to.

I set up two-step verification using SMS

Please note that SMS security codes are also unique and time-sensitive. If you're using SMS to receive a two-step verification code, be sure to enter the code as soon as it arrives.

Finally, please be sure to write down your emergency backup codes any time you enable or re-enable two step verification.
