#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.

USER_AUTH

: The entry point for [choice-based authentication] with

passwords, one-time passwords, and WebAuthn authenticators.
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. To activate this
setting, your user pool must be in the [ Essentials tier][2] or
higher.

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][3].

REFRESH_TOKEN_AUTH and REFRESH_TOKEN

: Receive new ID and access tokens when you pass a ‘REFRESH_TOKEN`

parameter with a valid refresh token as the value. For more
information, see [Using the refresh token][4].

CUSTOM_AUTH

: Custom authentication with Lambda triggers. For more information,

see [Custom authentication challenge Lambda triggers][5].

USER_PASSWORD_AUTH

: Client-side username-password authentication with the password

sent directly in the request. For more information about
client-side and server-side authentication, see [SDK authorization
models][6].

‘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 are specific to the InitiateAuthRequest$AuthFlow.

The following are some authentication flows and their parameters. Add a ‘SECRET_HASH` parameter if your app client has a client secret.

  • ‘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.

  • ‘USER_SRP_AUTH`: `USERNAME` (required), `SRP_A` (required), `DEVICE_KEY`.

  • ‘USER_PASSWORD_AUTH`: `USERNAME` (required), `PASSWORD` (required), `DEVICE_KEY`.

  • ‘REFRESH_TOKEN_AUTH/REFRESH_TOKEN`: `REFRESH_TOKEN` (required), `DEVICE_KEY`.

  • ‘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 send an ‘InitiateAuth` request, 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 sign-up

  • Pre authentication

  • User migration

When Amazon Cognito invokes the functions for these triggers, it passes a JSON payload as input to the function. This payload contains a ‘validationData` attribute with the data that you assigned to the `ClientMetadata` parameter in your `InitiateAuth` request. In your function, `validationData` can contribute to operations that require data that isn’t in the default payload.

‘InitiateAuth` requests invokes the following triggers without `ClientMetadata` 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 [ Using 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.

  SENSITIVE = [:auth_parameters, :client_id, :user_context_data, :session]
  include Aws::Structure
end

#session ⇒ String

The optional session ID from a ‘ConfirmSignUp` API request. You can sign in a user directly from the sign-up process with the `USER_AUTH` authentication flow. When you pass the session ID to `InitiateAuth`, Amazon Cognito assumes the SMS or email message one-time verification password from `ConfirmSignUp` as the primary authentication factor. You’re not required to submit this code a second time. This option is only valid for users who have confirmed their sign-up and are signing in for the first time within the authentication flow session duration of the session ID.

Returns:

#user_context_data ⇒ Types::UserContextDataType

Contextual data about your user session like the device fingerprint, IP address, or location. Amazon Cognito threat protection 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.

For more information, see [Collecting data for threat protection in applications].
