Trusted Email Profile


Use case: Many websites with a large installed-base of accounts that login with Email & password would like to become OpenID relying parties.  However they only way to support IDPs who provide a higher success rate then their current approach for both registration and login rates.  Instead of each website identifying those IDPs, they would like a central neutral organization like OIX to maintain a list of IDPs who meet certain known requirements.  The following profile lists those known requirements. 
 The IDP must:

  • support a PAPE request to indicate that the IDP's assertion should follow this specific certification profile
  • meet all requirements of the GSA OpenID ICAM Profile except the requirement to avoid sending PII to the RP
  • use an authentication scheme that is at least as strong as the suggested best practices for the ICAM profile
  • have a historic 99.5% uptime of its authentication and OpenID IDP system
  • NOT require the RP to pre-register with the IDP or enter into a legal contract with the IDP to use that IDP API (similar to the model of SMTP)
  • support OpenID discovery based on either the domain name (using directed identity) or an Email address in that domain (using webfinger)
  • support AX requests for the AX "email" parameter and return that parameter on every request, even if it has not changed
  • only return the email address that the logged in account receives over the open Internet via the IDP's SMTP service (and thus is equivalent to traditional email validation)
  • return a global, unchanging and non-recycled OpenID claimed URL for the account
  • show at most one page in 99% of the consent flows once the user is authenticated
  • default to NOT requiring the user to re-enter their password during the OpenID flow if the user had already been authenticated by the IDP before the OpenID request was made
  • default to auto-approving future logins by a user to the same RP
  • support checkid_immediate
  • support the PAPE openid.pape.max_auth_age parameter, though it can choose to always re-authenticate the user no matter what value is passed in that parameter
  • auto-detect mobile and non-JS browsers and show consent pages that a friendly for them
