Generally, we link Facebook and Instagram accounts to reduce the efforts that go in posting the same content or media on two different platforms. Before we move ahead to link the accounts you need to be the admin of the Facebook page.
Learn How To Be The Admin Of The Facebook Page
If you are the admin of the Facebook page, you can easily link your Instagram account with it and start sharing your post.
It is a two-way street! Yes, first you need to connect the Facebook Page with the account. Second, from your Instagram account link your Facebook account.
Once you are at your Facebook Page, on the top right side you can see the setting options.
Note: This is possible when you have a Business Account or else you would be prompted to convert your personal account into a business account.
In case if you no longer want to link your Instagram account to your Facebook Page, then you can just select Disconnect Account and confirm that you would like to remove the Instagram account.
Once again you would be prompted to enter your username and password to confirm and complete the process authentically.
