Easy - Modifying database data - RESOLVED

OK... I knew nothing about databases this morning... And I still really don't. The idea here is to create a security system with multiple user names and passwords. I would like to start out all users with the password "changeme," and after the first login, it will change their password. I found code below on Planet Source code and modified it to suit my needs; all except for writing the password back to the Access database.

I know this must be really simple... but I've never messed with databases before; I don't know anything about them.

VB Code:

Private mdbLogin As Database
 
Private Sub cmdOK_Click()
 
    Dim rstUsers As Recordset
    Dim newPassword As String
    
    If (Len(Trim(txtUserName.Text)) > 0) Then
        Set mdbLogin = OpenDatabase(App.Path & "\Login.mdb", False, False, ";pwd=AdmiN")
        Set rstUsers = mdbLogin.OpenRecordset("SELECT * FROM Users WHERE UserName='" & _
            Trim(txtUserName.Text) & "'")
    Else
        ShowError "Please enter a user name"
        Exit Sub
    End If
    
    With rstUsers
        If (.RecordCount > 0) Then
            If (.Fields("Password").Value = txtPassword.Text) Then
                    
                    'User has logged in
                    
                    LogEvent "User logged in: " & txtUserName
                    
                    If txtPassword = "changeme" Then
                    
                    Do
                    
                        newPassword = InputBox("This appears to be the first time you have logged in. Please enter a new password for your account. You are responsible for all activity which occurs on the computer while you are logged in.")
                    
                        If newPassword = "" Or newPassword = "changeme" Then
                            MsgBox "The password cannot be 'changeme' or blank. Please enter a different password.", vbCritical
                        Else
                            'Here's where I'm stuck, I have no idea what to do to update the data in the database
                            Exit Do
                        End If
                    
                    Loop
                    
                    End If
                    
                    Unload Me 'Allow user access to the computer
                
            Else
                LogEvent "Invalid password: " & txtUserName & ", " & txtPassword
                ShowError "The password you entered is invalid"
                txtPassword.SetFocus
                txtPassword.SelStart = 0
                txtPassword.SelLength = Len(txtPassword.Text)
            End If
        Else
            LogEvent "Invalid username: " & txtUserName & ", " & txtPassword
            ShowError "The user name you entered is invalid"
        End If
    End With
    
    rstUsers.Close
    Set rstUsers = Nothing
 
    mdbLogin.Close
    Set mdbLogin = Nothing
End Sub

Got it...

.Edit
!Password = newPassword
.Update

... is what I was looking for!
