VB.NET - How can I define a textbox that will not remember previously entered text?

I want to use a textbox for user to enter their password to login.  I need to fix the textbox so it won't remember previously entered text and show these as suggestions to choose from.  Is this possible?

I have used the form tag to try to fix this but will this work for all browsers?

Not if this is functionality offered by the browser itself.  You'd also want to set your password textbox to

TextMode="Password"

Thank you.  Looks like it works.
