Pour utiliser les API sans mot de passe intégrées dans les applications natives, assurez-vous d’activer l’autorisation **OTP sans mot de passe** en accédant à [Auth0 Dashboard > Applications > Applications](https://manage.auth0.com/#/applications) dans les paramètres de votre application sous **Paramètres avancés** > **Types d’autorisation**.

L’authentification sans mot de passe pour les applications natives se compose de deux étapes :

* Recueillez l’identifiant de l’utilisateur dans votre application (le courriel ou le numéro de téléphone de l’utilisateur) et faites un appel au point de terminaison `/passwordless/start` pour initier le flux sans mot de passe. L’utilisateur recevra un courriel ou un SMS avec un mot de passe à usage unique.
* Demandez à l’utilisateur le code à usage unique et faites un appel au point de terminaison `/oauth/token` pour obtenir des jetons d’authentification.

Voici quelques extraits de code qui peuvent être utilisés pour appeler ces points de terminaison API dans différents scénarios.
