How much PHP do you know? You could just calculate the time length between the last login and registration time (if they've never logged in yet), or between the last two logins. If it equals x amount of time, then delete'em. How complicated is your current script? I could probably help you more if you give me more info on how much you know and what kind of script you're working with.

Use cookies for your login script. Set it for an expiring time for each user. Or simply use seesions if your good with PHP. Run the sessions from a MySQL Databse too, thatll help you keep track for sure how long they stay logged in or not.

I don't know much at all! I'm using a free script. (Jpmaster77's Login Script)
What I need is to auto delete users and passwords from Mysql database after
a certain number of days. I can't find a free script that will do that.
I read that I could write a php script that will do this.....(by using cron to execute
it), but I don't know much about cron either. :o

WEll, I hope my tutorial wll help you, by for now, its at my latest test site if you want to go look and read up on it, it might help you as far as Kill Cookies go or even sessions so that you wont have t odo it manually from the Database. http://www.mtechhosting.com/site/mod...iewItems&vid=1

No registration as I said already that this is my test site.

This really should not be too hard. Depending on how you have your login, what information you store there. Add a date/time stamp. Set some kind of variable somewhere else. When ever that user or someone else or have a seperate script for it...check the difference between when the user /account was created and now see if the time is bigger than the variable which states how long a user is valid...it doesn't get any cheaper than this...

1 word. Sessions!!

You could of course use sessions to maintain a users logged in period, but the deleting will need to be handled by a cron executed periodic script.
To do this you would simply need to add a tmie stamp to each users database entry stating when they last logged in.
The cron'd script would then run a database query regularly, (say daily or weekly or whatever you need) which would check each users timestamp, compare it to the current time, and if it exceeds your x amount of time, delete the database row (all users details).

Please read the following documentation for a thorough and clear tutorial on using crons http://www.webmasters-central.com/t/cron.shtml

Hope this helps
