There are many OpenID providers. Since the Identity Provider will authenticate you, it is important that you select a reputable entity who will use a secure method to authenticate you. It is your responsibility to select a reliable Identity Provider. An exhaustive list of Identity Providers is available here.

Even though an OpenID provided by any provider could be used for registration, to simplify the sign-up procedure, we have partnered with a few of the providers.

1. MyOpenID is a leading identity provider, whose tools we have used for our development.
2. MyVidoop uses a novel authentication procedure that avoids phishing schemes and other insecurities.
