To manage admin rights on your Instagram page, you need to be the page owner or have been granted admin access by the owner. Here are the steps to manage admin rights:

1. Go to your Instagram profile and tap the three horizontal lines in the top right corner.
2. Tap “Settings” and then “Account”.
3. Under “Account”, tap “Page Roles”.
4. You’ll see a list of people who currently have access to your page. To add someone as an admin, tap “Add Person” and enter their Instagram username or email address.
5. Select the role you want to assign to the person. There are different roles you can assign, such as admin, editor, moderator, advertiser, or analyst.
6. Tap “Add” to confirm the changes.

To remove someone’s admin access, follow these steps:

1. Go to the “Page Roles” section under “Account”.
2. Find the person you want to remove and tap their name.
3. Tap “Remove From Page” and confirm the action.

Note that if you remove someone as an admin, they’ll lose all admin privileges and won’t be able to perform any actions on the page.

Make sure to only grant admin access to people you trust and who have a legitimate need to manage your page.
