Box integration authentication is unsuccessful when 2FA is enabled

In Popsync, the Box integration is unable to authenticate if Two-Factor Authentication (2FA) is enabled for your Box account.

Steps to reproduce

Enable 2FA for your Box account and attempt to log in to your Box account from Popsync to add it as an Image source. Box’s OAuth authentication flow is not working properly, and a mobile app can no longer authenticate using OAuth.

Expected result

By completing Box’s 2FA authentication process, users should be able to access Box as an Image source from Popsync.

Observed result

After entering the SMS code sent by Box, a “Sorry, we couldn’t find that page” error page displays, and the authentication fails.


  1. Disable 2FA on

  2. Clear all site cookes for the following:

  1. Re-enable 2FA and attempt to authenticate to again.

Note: Once you reenable 2FA, do not manually log out of Box or Popsync.
