Security question

[meldrape]

I have just completed an Access 2000 application. Now they want some way to sign in with a username and password. What is the easiest way to do this? When they sign in, how do I *capture* the username as a filter so the only report data they see uses the username as a filter?

I have never used Access security. It's just a plain, MDB file that lives on a computer in the office and 6 people have a shortcut to it. Thanks in advanced.
