You can make a simple password pop-up window by using the Prompt User For Input VI, it is an express VI on the Time & Dialog controls. You can configure it to return a string to your VI, then compare it to the actual password.

You could use the File I/O VI's to make a password file, and read it into the VI before you prompt the user, so the password is not actually stored in the VI.

maybe you want some encryption for your username/password files ?

then you can use this very simple XOR-"Encryption", which makes the text at least "unreadable" 2 humans, but it will not withstand any brute force cracking ;-)
