Activate login how?

Hello
I have just noticed that under /codebase/php/ with admin.php you can have login page.
How can I activate it so that each time before the spreadsheet is shown could be appeared?
And where should the user must be entered in the db?

I did not find any docs to read. If any exists could you please point out where to find them?

Thanks
