InitiateAuthResponse

The result of a successful and complete authentication request. This result is only returned if the user doesn't need to pass another challenge. If they must pass another challenge before they get tokens, Amazon Cognito returns a challenge in ChallengeName, ChallengeParameters, and Session response parameters.

This response parameter lists the available authentication challenges that users can select from in choice-based authentication. For example, they might be able to choose between passkey authentication, a one-time password from an SMS message, and a traditional password.

The name of an additional authentication challenge that you must respond to.

The required parameters of the ChallengeName challenge.

The session identifier that links a challenge response to the initial authentication request. If the user must pass another challenge, Amazon Cognito returns a session ID and challenge parameters.
