Page with no security (publicly accessible)

Hi All,
I have an issue of how can I, with ease, to enable a page which is publicly accessible (no password needed to view the page), once I enable my project with database security (security tab) of static permission.
For example, I have a project of 3 pages, ie: page1.php, page2.php, and page3.php ...

I want my page1.php is publicly accessible (no password needed and open to all to view).
When in security tab, I select <no login> for page1.php, PHPrunner actually remove my project (all pages of php) from security access, and all pages are open for public access.
Kindly advise.
Thanks and regards,
