I'm not sure if I understood your question correctly. The way I understood it was that you want the user to be able to change the username and password. Does he/she have to know the current username and password?

There's some code below that allows the user to change the username/password without knowing the old ones. If you want to know how to do that too, tell me.

Create 2 more text boxes and 1 more command button (text3, text4, and Command2).

Gerneral Declarations
dim username
dim password

Command2_Click()
username = text3.text
password = text4.text

Command1_Click()
if text1.text = username and text2.text = password then
msgbox "Correct login"
else msgbox "Incorrect login"
End if

I hope this helps.
