0To remove access, you must first switch to the specific Facebook Business Page from which you want to remove someone's access. This ensures you're making changes to the correct page.
After clicking the 3 dots next to the profile you want to remove, select "Remove Access". You'll then be prompted to enter your Facebook password to confirm your identity and the removal request. Finally, click "Confirm" to finalize the process.
In some cases, the removal of access might not be immediate. You may need to refresh the page or go back to your profile to approve the removal request. However, in other instances, the access might be removed instantly.
This step is a security measure by Facebook to ensure that only you, the account holder, can make changes to page access. It helps prevent unauthorized removal of access by others.
