This is a rapid and simple process, plus your Facebook login info is required.
- Launch Instagram and toggle over to your account profile (seen in the bottom toolbar).
- Click the 3 bars and choose “Settings.”
- Click “Account” and then choose “Linked Accounts.”
- Click “Facebook” and get yourself logged into your Facebook account to confirm that you wish to link your Facebook account to Instagram.
Before you share any posts, you must know that if you own a private Instagram, whatever you share to other social networks, like Facebook, will become public.
