#auth_flow ⇒ String

The authentication flow that you want to initiate. Each ‘AuthFlow` has linked `AuthParameters` that you must submit. The following are some example flows and their parameters.

  • ‘USER_AUTH`: Request a preferred authentication type or review available authentication types. From the offered authentication types, select one in a challenge response and then authenticate with that method in an additional challenge response.

  • ‘REFRESH_TOKEN_AUTH`: Receive new ID and access tokens when you pass a `REFRESH_TOKEN` parameter with a valid refresh token as the value.

  • ‘USER_SRP_AUTH`: Receive secure remote password (SRP) variables for the next challenge, `PASSWORD_VERIFIER`, when you pass `USERNAME` and `SRP_A` parameters.

  • ‘USER_PASSWORD_AUTH`: Receive new tokens or the next challenge, for example `SOFTWARE_TOKEN_MFA`, when you pass `USERNAME` and `PASSWORD` parameters.

*All flows*

USER_AUTH

: The entry point for sign-in with passwords, one-time passwords,

and WebAuthN authenticators.

USER_SRP_AUTH

: Username-password authentication with the Secure Remote Password

(SRP) protocol. For more information, see [Use SRP password
verification in custom authentication flow][1].

REFRESH_TOKEN_AUTH and REFRESH_TOKEN

: Provide a valid refresh token and receive new ID and access

tokens. For more information, see [Using the refresh token][2].

CUSTOM_AUTH

: Custom authentication with Lambda triggers. For more information,

see [Custom authentication challenge Lambda triggers][3].

USER_PASSWORD_AUTH

: Username-password authentication with the password sent directly

in the request. For more information, see [Admin authentication
flow][4].

‘ADMIN_USER_PASSWORD_AUTH` is a flow type of [AdminInitiateAuth] and isn’t valid for InitiateAuth. ‘ADMIN_NO_SRP_AUTH` is a legacy server-side username-password flow and isn’t valid for InitiateAuth.

end

#auth_parameters ⇒ Hash<String,String>

The authentication parameters. These are inputs corresponding to the ‘AuthFlow` that you’re invoking. The required values depend on the value of ‘AuthFlow`:

  • For ‘USER_AUTH`: `USERNAME` (required), `PREFERRED_CHALLENGE`. If you don’t provide a value for ‘PREFERRED_CHALLENGE`, Amazon Cognito responds with the `AvailableChallenges` parameter that specifies the available sign-in methods.

  • For ‘USER_SRP_AUTH`: `USERNAME` (required), `SRP_A` (required), `SECRET_HASH` (required if the app client is configured with a client secret), `DEVICE_KEY`.

  • For ‘USER_PASSWORD_AUTH`: `USERNAME` (required), `PASSWORD` (required), `SECRET_HASH` (required if the app client is configured with a client secret), `DEVICE_KEY`.

  • For ‘REFRESH_TOKEN_AUTH/REFRESH_TOKEN`: `REFRESH_TOKEN` (required), `SECRET_HASH` (required if the app client is configured with a client secret), `DEVICE_KEY`.

  • For ‘CUSTOM_AUTH`: `USERNAME` (required), `SECRET_HASH` (if app client is configured with client secret), `DEVICE_KEY`. To start the authentication flow with password verification, include `ChallengeName: SRP_A` and `SRP_A: (The SRP_A Value)`.

For more information about ‘SECRET_HASH`, see [Computing secret hash values]. For information about `DEVICE_KEY`, see [Working with user devices in your user pool].

end

#client_metadata ⇒ Hash<String,String>

A map of custom key-value pairs that you can provide as input for certain custom workflows that this action triggers.

You create custom workflows by assigning Lambda functions to user pool triggers. When you use the InitiateAuth API action, Amazon Cognito invokes the Lambda functions that are specified for various triggers. The ClientMetadata value is passed as input to the functions for only the following triggers:

  • Pre signup

  • Pre authentication

  • User migration

When Amazon Cognito invokes the functions for these triggers, it passes a JSON payload, which the function receives as input. This payload contains a ‘validationData` attribute, which provides the data that you assigned to the ClientMetadata parameter in your InitiateAuth request. In your function code in Lambda, you can process the `validationData` value to enhance your workflow for your specific needs.

When you use the InitiateAuth API action, Amazon Cognito also invokes the functions for the following triggers, but it doesn’t provide the ClientMetadata value as input:

  • Post authentication

  • Custom message

  • Pre token generation

  • Create auth challenge

  • Define auth challenge

  • Custom email sender

  • Custom SMS sender

For more information, see [ Customizing user pool Workflows with Lambda Triggers] in the *Amazon Cognito Developer Guide*.

<note markdown=“1”> When you use the ‘ClientMetadata` parameter, note that Amazon Cognito won’t do the following:

* Store the `ClientMetadata` value. This data is available only to
 Lambda triggers that are assigned to a user pool to support custom
 workflows. If your user pool configuration doesn't include
 triggers, the `ClientMetadata` parameter serves no purpose.

  • Validate the ‘ClientMetadata` value.

  • Encrypt the ‘ClientMetadata` value. Don’t send sensitive information in this parameter.

#user_context_data ⇒ Types::UserContextDataType

Contextual data about your user session, such as the device fingerprint, IP address, or location. Amazon Cognito advanced security evaluates the risk of an authentication event based on the context that your app generates and passes to Amazon Cognito when it makes API requests.
