Configure an MFA-Only Flow Using a Login Hint Token
Number of APIs: 17
This activity shows you how to create an MFA only authentication flow using a login_hint_token to identify and authenticate the end-user without needing to encode the entire authentication request in a signed JWT. 
The following operations are supported by the PingOne APIs:
- Create an application
- Create a sign-on policy
- Create an SMS sign-on policy action
- Create a user
- Create a device authentication policy
- Initiate an authorize request using a login_hint_token
- Use the OTP check API to complete the MFA action
Prerequisites
Get an access token from the worker application that you created in Getting Started with the PingOne APIs. To get a token from a different worker application in an alternate sandbox environment, run the token request endpoint using the client ID and client secret of your chosen worker app to authenticate the request. For more information, see GET a Worker Application Access Token.
Workflow order of operations
To complete an MFA only authentication flow, the following tasks must be completed successfully:
- Make a - POSTrequest to- /environments/{{envID}}/applicationsto add a new application to the specified environment.
- Make a - GETrequest to- /environments/{{envID}}/applications/{{appID}}/secretto return the new application's- secretattribute, which is needed for the token request.
- Make a - GETrequest to- /environments/{{envID}}/resourcesto return a list of all resource entities associated with the specified environment.
- Make a - GETrequest to- /environments/{{envID}}/resources/{{resourceID}}/scopesto list all scopes associated with a specified resource.
- Make a - POSTrequest to- /environments/{{envID}}/applications/{{appID}}/grantsto create a new resource access grant for the application.
- Make a - POSTrequest to- /environments/{{envID}}/signOnPoliciesto create a new sign-on policy.
- Make a - POSTrequest to- /environments/{{envID}}/signOnPolicies/{{signOnPolicyID}}/actionsto define the SMS MFA action associated with this sign-on policy.
- Make a - POSTrequest to- /environments/{{envID}}/applications/{{appID}}/signOnPolicyAssignmentsto associate the sign-on policy with the application.
- Make a - POSTrequest to- /environments/{{envID}}/populationsto create a new population resource.
- Make a - POSTrequest to- /environments/{{envID}}/usersto create a user who will be assigned to the new population resource.
- Make a - POSTrequest to- /environments/{{envID}}/users/{{userID}}/passwordto set the new user's password.
- Make a - POSTrequest to- /environments/{{envID}}/users/{{userID}}/mfaEnabledto enable MFA actions for this user.
- Make a - POSTrequest to- /environments/{{envID}}/deviceAuthenticationPoliciesto create the device authentication policy.
- Make a - POSTrequest to- /environments/{{envID}}/users/{{userID}}/devicesto associate an SMS MFA device with this user.
- Make a - POSTrequest to- /{{envID}}/as/authorizeto obtain an authorization grant. This request starts the authorization flow.
- To complete the SMS MFA action, make a - POSTrequest to- GET /{{envID}}/flows/{{flowID}}and provide the one-time passcode.
- Make a - GETrequest to- /{{envID}}/as/resume?flowId={{flowID}}to call the resume endpoint and return the auth code.
