Since you are logged in as an administrator, you do not have to enter in access codes to private galleries, log in as a customer (if required to do so in the Settings > Basic Settings) and your gallery views are not counted in the stats.
You can also edit the text on these pages with the text edit mode below. Some text you may not be able to edit here is edited in the admin in the Customize > Text & Language.
You can put in a text field [ACCESS_GALLERY_FORM] and it will display a small access gallery form.
You can put in a text field [CUSTOMER_NAME] and it will display the customer's first name.
