Annie Applicant wants to use an application service. The application service permits both login with an application service credential, or login with an AdmitMe account. Annie recognizes that she has an AdmitMe account, and clicks on that button. Shedoesn't have a local account yet, and there's an explanation on the page that tells her about all the benefits of using AdmitMe instead of a local account. She chooses to click on the AdmitMe button and she creates a new AdmitMe account. Following account creation, she's directed back to the AdmitMe IdP to authenticate. After successfully authenticating, AdmitMe sends back an assertion describing the authentication, the verification level associated with her account, her AdmitMe identifier, and optionally a set of attributes. The application service optionally creates or loads a local representation of Annie keyed by her AdmitMe identifier which is used to store additional local data about her.
The next time Annie returns to the service, she chooses to login with AdmitMe. Since she already has an account, she clicks the AdmitMe button. After successfully authenticating, AdmitMe sends back an assertion describing the authentication, the verification level associated with her account, her AdmitMe identifier, and optionally a set of attributes. The application service optionally loads the local representation of Annie.
