One use login/password

i need a scritp php maybe java that can generates or register accounts (user/pass) valid for only once so i can restrict the access to a certain information in my site, anyone knows where can i find something?

thx

How will these accounts be stored? Are you looking at using a database such as MySQL, or do you want to do something like Apache-level authentication through .htaccess/.htpasswd?

If you use MySQL, this is VERY simple to do. You can find tutorials making a login system with PHP/MySQL... however, the difference is, upon successful login, you'll need to execute one more SQL query in the form of "DELETE FROM..." to remove that username and password from the table.

yeah i have MySQL, but im dont have a good lvl programing and im not familiar with function and stuff, but i can make an "overview understanding" of it. I have complete control of the host, that's what i am looking for a pre-made code. Thx

yeah i need to code a login/logout script with php/mysql/session but i don't know how

If your willing to pay than take it to the "Hire A Programmer" forum... else.. have you tried searching google?
