Sign-in and Sign-up policy with direct link to sign-up

This sample adds a direct link to the sign-up page. A relying party application can include a query string parameter option=signup that takes the user directly to the sign-up page

Live demo

To checkout the user experience of this policy, follow these steps:

1. Run the B2C_1A_Demo_SignUpSignin_DeepLink policy. This authorization request specifies the option=signup query string parameter, which takes you directly to the sign-up page.
2. Run the B2C_1A_Demo_SignUpSignin_DeepLink policy again. This time the authorization request is without the option=signup query string parameter, which takes you the the sign-up or sign-in page instead.

Scenario

To add the direct link to the sign-up page:

1. At the begging of the sign-up and sign-in user journey, add an orchestration step that reads the option claim resolver. The Get-sign-up-claim-resolver technical profile also checks the value of the option claim, and set the value of the Boolean signUpFlow claim.

   <OrchestrationStep Order="1" Type="ClaimsExchange">
     <ClaimsExchanges>
       <ClaimsExchange Id="Get-sign-up-claim-resolver" TechnicalProfileReferenceId="Get-sign-up-claim-resolver" />
     </ClaimsExchanges>
   </OrchestrationStep>

2. Then add a new orchestration step that invokes the LocalAccountSignUpWithLogonEmail sign-up technical profile. This steps runs only if the signUpFlow is True.

   <OrchestrationStep Order="2" Type="ClaimsExchange">
     <Preconditions>
       <Precondition Type="ClaimEquals" ExecuteActionsIf="true">
         <Value>signUpFlow</Value>
         <Value>False</Value>
         <Action>SkipThisOrchestrationStep</Action>
       </Precondition>
     </Preconditions>
     <ClaimsExchanges>
       <ClaimsExchange Id="SignUpExchange" TechnicalProfileReferenceId="LocalAccountSignUpWithLogonEmail" />
     </ClaimsExchanges>
   </OrchestrationStep>

3. Add a precondition to the the CombinedSignInAndSignUp orchestration step. Make is run only if the signUpFlow is False.

   <OrchestrationStep Order="3" Type="CombinedSignInAndSignUp" ContentDefinitionReferenceId="api.signuporsignin">
     <Preconditions>
       <Precondition Type="ClaimEquals" ExecuteActionsIf="true">
         <Value>signUpFlow</Value>
         <Value>True</Value>
         <Action>SkipThisOrchestrationStep</Action>
       </Precondition>
     </Preconditions>
     <ClaimsProviderSelections>
       <ClaimsProviderSelection TargetClaimsExchangeId="FacebookExchange" />
       <ClaimsProviderSelection ValidationClaimsExchangeId="LocalAccountSigninEmailExchange" />
     </ClaimsProviderSelections>
     <ClaimsExchanges>
       <ClaimsExchange Id="LocalAccountSigninEmailExchange" TechnicalProfileReferenceId="SelfAsserted-LocalAccountSignin-Email" />
     </ClaimsExchanges>
   </OrchestrationStep>

Set the authorization request

To direct the user to the sign-up page, in the authorization request add the option=signup query string parameter.

The following example takes the user to the landing page (sign-up or sign-in):

https://yourtenant.b2clogin.com/yourtenant.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1A_SignUp_SignIn_with_link_to_sign_up&client_id=63ba0d17-c4ba-47fd-89e9-31b3c2734339&nonce=defaultNonce&redirect_uri=https%3A%2F%2Fjwt.ms&scope=openid&response_type=id_token

If you add the option=signup parameter, the user is taken directly to the sign-up page.

https://yourtenant.b2clogin.com/yourtenant.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1A_SignUp_SignIn_with_link_to_sign_up&client_id=63ba0d17-c4ba-47fd-89e9-31b3c2734339&nonce=defaultNonce&redirect_uri=https%3A%2F%2Fjwt.ms&scope=openid&response_type=id_token&option=signup`
