An Account Chooser is designed to be a layer you can add on top of your website's existing sign in and registration flows. By integrating your website with an Account Chooser you should expect to increase registration and sign in rates, as well as reduce costs from users who have trouble logging into their account. Because accountchooser.com keeps a single list of accounts in the user's browser, the more websites who use it, the more likely the user will have already added their account to the list.
Your website can use an Account Chooser WITHOUT becoming a relying party to identity providers. In fact, if your site plans to become a relying party in the future, you should consider deploying an account chooser first because it can generally avoids some of the user confusion when your site does begin to support a mix of password based logins and identity provider logins. However we suggest that eventually most sites should both integrated with the accountchooser.com service and become a relying party.

It is also possible to deploy these techniques on your own since they are based on standards as described in the working group section of the main site.
