To delete a profile on Facebook (specifically an additional or secondary profile linked to your main account), follow these steps:

1. Log in to your Facebook account.
2. Click on your profile photo at the top right corner.
3. Select Settings & Privacy, then click Settings.
4. On the left menu, click Account Center.
5. In Account Center, go to Personal Details.
6. Click Account Ownership and Control.
7. Select Deactivation and Deletion.
8. Choose the profile you want to delete (make sure it is the correct additional profile).
9. Select Delete Additional Facebook Profile , then click Continue.
10. Provide a reason for deletion if prompted, then continue.
11. Enter your Facebook account password to confirm.
12. Confirm the deletion.

After this, the additional profile will be deleted, but your main Facebook account will remain active. You have 30 days to reactivate the profile if you change your mind

. This process is for deleting additional profiles linked to your main Facebook account, not for deleting the entire Facebook account itself. If you want to delete your entire Facebook account, the steps differ and involve account deactivation or deletion through your personal details and account ownership settings
