OpenID is a decentralized protocol that allows single sign-on across websites, enabling users to log in to multiple websites without needing separate usernames and passwords for each one. The document recommends that if a web application has learners as customers, it should implement OpenID to allow users to log in with their existing identities from other services like educational institutions or Facebook. Many smaller websites and Facebook already use OpenID, and more major companies are becoming OpenID identity providers as well, highlighting its growing importance for user authentication on the web.

2. The take-away
If you are building a web application...
And you anticipate learners amongst your
customers
Be an OpenID relying party.

5. Standards based, open
source system for single
sign-on across or within
organisational boundaries.
Sites can make informed
authorisation decisions for
Decentralised, light- individual access of
weight protocol for protected online resources
single sign-on and
portable identity

6. OpenID in the wild
Many “smaller” Web 2.0 services are
OpenID relying parties.
Notably, so too is Facebook.
More “brand names” are OpenID identity
providers.

7. Educational Institutions
Educational institutions already collect and
manage identity.
Becoming an identity provider for them is
trivial.
Becoming a relying party is transformative.
