I ask the same question as sir.prize.."Why do you need a new password"?
If you are able to log into your profile (by whatever means) it should be a simple matter for you to bookmark the page for future reference and accessing AB.
Once you have bookmarked it you should then be able to put a short cut icon on your desktop ( Computer screen) and be able to click it for immediate access to AB.
Having said what I have, I honestly can't fully remember how I did it. Nevertheless, I feel sure you will get there by trial and error.
Best wishes ...Ron
