By default, when you connect Facebook to Instagram, it is linked with your Facebook profile and hence, all the posts are published on your profile. You need to verify and connect your Facebook page instead of the profile to Instagram.
Unlinking your Instagram and Facebook accounts can be done from the Instagram app or the website. Go to Profile > Menu > Settings > Accounts Center > Accounts & profiles. Select an account and tap Remove from Accounts Center.
Under Preferences, tap Share Settings and then tap Facebook. Next, you will see a slider for Share Likes To Timeline. Make sure it is turned off.
There isn’t an option that allows you to disconnect your Facebook account and your Instagram page on Facebook. In fact, the only way to unlink the two is by using the Instagram app on mobile devices. Of course, you can do it via an iPhone or an Android device.
As mentioned above, Instagram automatically picks up the Facebook profile that is registered with the Facebook app on your phone. If you want to change the Facebook account, you need to log out from the Facebook app first (if installed).
How do you stop people from sharing your Instagram?
To disconnect and stop sharing your Instagram posts to another social network:
- Go to your profile and tap .
- Tap Settings.
- Tap Account.
- Tap Sharing to Other Apps, then tap the social network you’d like to unlink.
- Tap Unlink Account (iOS) or Unlink (Android).
- Tap Yes, I’m sure.
