abstract = {Much of the content and structure of the Web remains
inaccessible to evaluate at scale because it is gated by user
authentication. This limitation restricts researchers to examining only
a superficial layer of a website: the landing page or public,
search-indexable pages. Since it is infeasible to create individual
accounts across thousands of webpages, we examine the prevalence of
Single Sign-On (SSO) on the web to explore the feasibility of using a
few accounts to authenticate to many sites. We find that 58\% of the top
10K websites with logins are accessible with popular 3rd-party SSO
providers, such as Google, Facebook, and Apple, indicating that
leveraging SSO offers a scalable solution to access a large volume of
user-gated content.},
