Instagram supports 2FA but does NOT support enabling it via web browser:
If I can't get a QR code, I'm not sure how I'm going to add it to 1Password. The instagram app allows you to "Set Up Manually" which produces a random key string to enter into your authenticator app - but I don't see a way to manually enter a key string in 1Password.
Is there a way to make 2FA work with Instagram?
