These open Instagram directly in a new tab. You'll need to be logged in.
You do not need the Instagram app installed to delete your account - in fact, permanent deletion is only available through a browser, whether that is on your phone, a laptop, or a shared computer.
You will need to be logged in to reach this page, so if you cannot remember your password, use Instagram's Forgot password link on the login screen first to reset it via your email or phone number on file, then come back and follow the steps above.
If you are on a computer that is not yours, remember to log out fully afterward and clear the browser's saved password if you entered one, so the next person using that device cannot access anything.
If you cannot log in and cannot reset your password either, standard account deletion is not possible. In that case, Instagram's own account recovery process (accessible from the login screen) is the only path back in before you can request deletion.
