Enroll and Challenge Push Authenticators
Auth0 provides a built-in MFA enrollment and authentication flow using Universal Login. However, if you want to create your own user interface, you can use the MFA API to accomplish it.
You can enroll and challenge users using push notifications with the Guardian application or SDK using the MFA API.
Prerequisites
Before you can use the MFA APIs, you'll need to enable the MFA grant type for your application. Go to Auth0 Dashboard > Applications > Advanced Settings > Grant Types and select MFA.
Configure Push as a factor in the Dashboard or using the Management API.
Enroll with push
Get MFA token
Depending on when you are triggering enrollment, you can obtain an access token for using the MFA API in different ways:
If you are enrolling during authentication, see Authenticate With Resource Owner Password Grant and MFA.
If you want to let the user enroll a factor at any moment, see Manage MFA Factor Enrollments.
Enroll authenticator
Make a POST
request to the MFA Associate endpoint to enroll the user's authenticator. The bearer token required by this endpoint is the MFA token obtained in the previous step.
To enroll with push, set the authenticator_types
parameter to [oob]
and the oob_channels
parameter to [auth0]
.
curl --request POST \
--url 'https://{yourDomain}/mfa/associate' \
--header 'authorization: Bearer MFA_TOKEN' \
--header 'content-type: application/json' \
--data '{ "authenticator_types": ["oob"], "oob_channels": ["auth0"] }'

If successful, you receive a response like this:

"authenticator_type": "oob",
"barcode_uri": "otpauth://totp/tenant:user?enrollment_tx_id=qfjn2eiNYSjU3xID7dBYeCBSrdREWJPY&base_url=tenan",

If you get a User is already enrolled
error, the user already has an MFA factor enrolled. Before associating another factor with the user, you must challenge the user with the existing factor.
If this is the first time the user is associating an authenticator, you'll notice the response includes recovery_codes
. Recovery codes are used to access the user's account in the event that they lose access to the account or device used for their second-factor authentication. These are one-time usable codes, and new ones are generated as necessary.
Confirm push enrollment
To confirm the enrollment, the end user will need to scan a QR code with the barcode_uri
in the Guardian application, within the next 5 minutes.
Once that is done, the Guardian application will notify Auth0 that the user enrolled successfully. To know if that happened, poll the Auth0 Token endpoint with the oob_code
returned by the MFA Associate endpoint call.

At this point, the authenticator is fully associated and ready to be used, and you have the authentication tokens for the user.
You can check at any point to verify whether an authenticator has been confirmed by calling the MFA Authenticators endpoint. If the authenticator is confirmed, the value returned for active
is true
.
Challenge with push
Get MFA token
Get an MFA token following the steps described in Authenticate With Resource Owner Password Grant and MFA.
Retrieve enrolled authenticators
To challenge the user, you need the authenticator_id
for the factor you want to challenge. You can list all enrolled authenticators using the MFA Authenticators endpoint:
curl --request GET \
--url 'https://{yourDomain}/mfa/authenticators' \
--header 'authorization: Bearer MFA_TOKEN' \
--header 'content-type: application/json'
