The PP Authorizer is a plugin for Chrome web browser, which checks every page to have an "A" tag or "INPUT hidden" tags having "pp-authorizer" class and prompts to move to their links.

It is a solution to the problem about anonymous authentication.

The first problem with anonymous authentication is that users can't be sure about the reliability of the site they log into. To address this issue, a protocol should not allow the automatic redirection from a site of lower reliability to a site of higher reliability.

Second, if a site wants to connect to the authentication provider, it must have the site's information in the redirection URL, and the remaining necessity is to have a bookmarklet or add-on that follows the link after checking that the link included in the page is correct.

With this, the PP Authorizer has been developed.
