Crowd サポート

With CrowdID, you can use your 'OpenID' (also called an OpenID URL or identifier) to log in to a website that supports the OpenID protocol.

To log in to a website which supports OpenID,

Go to the login page of the website you want to visit.
Look for the OpenID login section.
Sometimes the OpenID login will be on the same page as the standard login. Other sites will have a separate OpenID login page.
Type or paste your OpenID into the login text box.
Usually, you must enter the full OpenID. In some sites, you can enter the OpenID without 'http://'
Click the login button. The button will probably be labeled 'Log in', 'Sign in' or 'Go'.

One of the following things will happen now:

If you have not already logged in to CrowdID during this browser session, you will see the CrowdID login page.
If you have already logged in to CrowdID and you have previously instructed CrowdID to allow this website always, then you will be logged straight into the website.
If you have already logged in to CrowdID but have not previously set this site to "Allow Always", then CrowdID will ask you to approve the login.
If your administrator has blocked access to this website, CrowdID will display an 'OpenID Verification Error' message.
