The Account Access area on the My Account tab is where you can see who else has access to your AdSense account. Unless you specifically grant an organization or another person access to the account, you should have no one else listed here.
If you’re using Blogger or some other applications (such as FeedBurner) with AdSense, that organization needs to have access. Keep in mind that the company can’t see your earning statements or make changes to your account beyond the changes that you authorize while setting up or changing ads. They’re still listed as hosts in your Account Access area — someone who is hosting your blog, RSS feed, or other aspect of the Web site on which you have ads displayed.
You can disable any and all hosting applications at any time by clicking the blue Disable Access link to the right of the hosting company’s name. After you click that link, however, the account no longer has access to the elements of your account needed to allow you to show ads through that service; so the ads that you have active no longer display, or if they do, they display with errors.
Unless you’ve changed your mind about having ads on your blog or in your RSS feed, you shouldn’t adjust the status of these hosts. Allow them to have the access they need to ensure that your ads continue to display properly
You can’t add multiple users to an AdSense account. You can share your username and password with others but you can’t physically add an additional user to your account. If you have an account that you want to share with your spouse or partner (or some other member of your staff), he must use your login.
When you allow someone to use your username and password to access your AdSense account, she has all the same privileges that you do, meaning she can change your account in any way she chooses. She can change ad types and placement, she can change reports, and she can even change your password and lock you out of the account.
Use caution if you plan to share your account with someone. Make sure it’s someone you trust. Better yet, don’t share. I know, you’ve been told all your life that sharing is good. In this case though, go ahead and share reports and information gleaned from your AdSense account, but keep actual access to the account to yourself, just to be on the safe side.
