Pour répondre à une stimulation d’authentification

Il existe de nombreuses manières de répondre aux différentes stimulations d’authentification, en fonction de votre flux d’authentification, de la configuration du groupe d’utilisateurs et des paramètres utilisateur. L’exemple admin-respond-to-auth-challenge suivant fournit un code d’authentification MFA par TOTP pour diego@example.com et termine la connexion. La mémorisation des appareils de ce groupe d’utilisateurs est activée, de sorte que le résultat de l’authentification renvoie également une nouvelle clé d’appareil.

aws cognito-idp admin-respond-to-auth-challenge \
    --user-pool-id us-west-2_EXAMPLE \
    --client-id 1example23456789 \
    --challenge-name SOFTWARE_TOKEN_MFA \
    --challenge-responses USERNAME=diego@example.com,SOFTWARE_TOKEN_MFA_CODE=000000 \
    --session AYABeExample...
