Initiates the authentication request.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

auth_flow: Option<AuthFlowType>

The authentication flow for this call to run. The API action will depend on this value. For example:

• REFRESH_TOKEN_AUTH takes in a valid refresh token and returns new tokens.

• USER_SRP_AUTH takes in USERNAME and SRP_A and returns the SRP variables to be used for next challenge execution.

• USER_PASSWORD_AUTH takes in USERNAME and PASSWORD and returns the next challenge or tokens.

Valid values include:

• USER_SRP_AUTH: Authentication flow for the Secure Remote Password (SRP) protocol.

• REFRESH_TOKEN_AUTH/REFRESH_TOKEN: Authentication flow for refreshing the access token and ID token by supplying a valid refresh token.

• CUSTOM_AUTH: Custom authentication flow.

• USER_PASSWORD_AUTH: Non-SRP authentication flow; user name and password are passed directly. If a user migration Lambda trigger is set, this flow will invoke the user migration Lambda if it doesn't find the user name in the user pool.

ADMIN_NO_SRP_AUTH isn't a valid value.

auth_parameters: Option<HashMap<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_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.

client_metadata: Option<HashMap<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

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

When you use the ClientMetadata parameter, remember 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 use Amazon Cognito to provide sensitive information.

client_id: Option<String>

The app client ID.

analytics_metadata: Option<AnalyticsMetadataType>

The Amazon Pinpoint analytics metadata that contributes to your metrics for InitiateAuth calls.

user_context_data: Option<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.

Implementations

impl InitiateAuthInput

pub fn auth_flow(&self) -> Option<&AuthFlowType>

The authentication flow for this call to run. The API action will depend on this value. For example:

• REFRESH_TOKEN_AUTH takes in a valid refresh token and returns new tokens.

• USER_SRP_AUTH takes in USERNAME and SRP_A and returns the SRP variables to be used for next challenge execution.

• USER_PASSWORD_AUTH takes in USERNAME and PASSWORD and returns the next challenge or tokens.

Valid values include:

• USER_SRP_AUTH: Authentication flow for the Secure Remote Password (SRP) protocol.

• REFRESH_TOKEN_AUTH/REFRESH_TOKEN: Authentication flow for refreshing the access token and ID token by supplying a valid refresh token.

• CUSTOM_AUTH: Custom authentication flow.

• USER_PASSWORD_AUTH: Non-SRP authentication flow; user name and password are passed directly. If a user migration Lambda trigger is set, this flow will invoke the user migration Lambda if it doesn't find the user name in the user pool.

ADMIN_NO_SRP_AUTH isn't a valid value.
