Hide password

Hello!

I'm new here. And i am noob in Microsoft Access. I just try to do something :).

I want to make a form of authentication in Microsoft Access.

I have this code:

Option Compare Database
Private Sub Form_Load()
Dim PassWord As String
PassWord = InputBox("Enter the password for the seller")
If PassWord = "seller" Then
' Open Form
DoCmd.OpenForm "seller"
DoCmd.GoToRecord , , acNewRec
DoCmd.Close acForm, "seller authentication"
Else
MsgBox ("Wrong password!")
DoCmd.Close acForm, "seller authentication"
End If
End Sub

Where am I supposed to add something that would hide the password? Like: **** or something.

Or if I can do it so please give me some advice.

Thank you so much! :)
