Hi Mary,
I assume that you mean that your password fails when you try to log on to the SAM website. (The SAM software does not require a password.)
I have not heard from anyone else with this problem -- you should not have to change your password each time you log on to the website.
When you try to log on, what link do you click? There are login links on the Support Forum page and one that appears at the top right of every page.
Best regards,
Paul.
