You can enable third-party applications for your tenant. See First-Party and Third-Party Applications for details on the differences between the two types of applications.
  1. Update your application’s ownership to third-party in Auth0. By default, applications registered in Auth0 are first-party applications. If you want your application to be a third-party application, you must update its ownership.
  2. Promote the connections you will use with third-party applications to domain level in Auth0. Third-party applications can only authenticate users from connections flagged as domain-level connections. Domain-level connections can be enabled for selected first-party applications while also being open to all third-party application users for authentication.
  3. Update your application’s login page. If you use Lock in the Universal Login Page, you must also:
    1. Upgrade to Lock version 11 or later.
    2. Set the __useTenantInfo: config.isThirdPartyClient flag when instantiating Lock.
    3. For Private Cloud users only: Set the configurationBaseUrl option to https://{config.auth0Domain}/ when instantiating Lock.

​
Access token current_user_* scopes

Neither first- nor third-party applications can use to invoke endpoints. Instead, they should get with the following current_user_* scopes required by each endpoint:
ScopeEndpoint
read:current_userList or search users
Get a user
Get user MFA enrollments
update:current_user_metadataUpdate a user
Delete a user’s multi-factor provider
create:current_user_device_credentialsCreate a device public key
delete:current_user_device_credentialsDelete a device credential
update:current_user_identitiesLink a user account
Unlink a user identity
