Instagram oAuth login with Facebook account

I'm trying to build a connection to the Instagram API using the instagram-oauth gem. However, when I open the oauth url, I'm not able to log into my Instagram account via Facebook. Only username/password is shown. Do I have to activate Facebook login support?

How do I get the auth code for Instagram?

Click your profile picture in the top right, then click Settings. Click Privacy and Security from the menu on the left. Scroll down to Two-Factor Authentication, then click Edit Two-Factor Authentication Setting. Click Get Backup Codes, then click Get New Codes.

Does Instagram have OAuth?

Instagram Basic Display API, an OAuth2 API, and enables you to grant access to your basic Instagram account data to a third-party app.

Instagram's API requires OAuth 2.0 and it does not support logging in to Instagram with Facebook. OAuth launches the Instagram login via a prebuilt, un-editable web browser, so this functionality is not possible at this point in time.
