title: Azure B2C Single Sign-On from iFrame
body: <p>I have 2 sites using Azure AD B2c for authentication.  One site is embedded in the other using an iFrame.  Independently, auth works fine for each, but when inside an iframe, the site is unable to access the login page because it disallows iframes.  I really just need SSO to work but I can't find any documentation on how to do this.</p>
