Database trial and authentication key

[ITguy1981]

I've got to present my database to a customer in two days and the beta is almost complete. I would however like put add a lockout after a specific date and prompt the user to input a key to continue using the software. In my mind I was thinking about making a password table, having some type of on load event of my splash screen to check the date I chose for it to expire, if it's expired open a form that would allow the user to enter a key or click cancel that would "quit" access. I'm not sure how to go about the code of actually having the password entered in verified to a stored password in a table. I'm not too worried about other security options as far as piracy because even if I hid the tables and forms the user would have no idea how to unhide them. I just need a way to keep them from continuing to use my beta and not purchase the final database. I realize I can lock the amount of entries that can be entered in to tables, but I'd rather go with a password/key type of method. I found a thread which seemed like it had a good database example I could use, but it was an older version of access and didn't convert properly. Thank you in advance for any help that can be offered.

Thank you for the reply. I've found a low security issue to resolve most of my problem. I was wondering. Is there a way to clear the tag entry of a form? I've tried to look at something like docmd.deleteobject, but I have no idea how to reference the tag on the form.
