Overview

The responses to the challenge that you received in the previous request. Each challenge has its own required response parameters. The following examples are partial JSON request bodies that highlight challenge-response parameters.

You must provide a SECRET_HASH parameter in all challenge responses to an app client that has a client secret. Include a ‘DEVICE_KEY` for device authentication.

SELECT_CHALLENGE

: ‘“ChallengeName”: “SELECT_CHALLENGE”, “ChallengeResponses”: 

"USERNAME": "[username]", "ANSWER": "[Challenge name]"`

Available challenges are `PASSWORD`, `PASSWORD_SRP`, `EMAIL_OTP`,
`SMS_OTP`, and `WEB_AUTHN`.

Complete authentication in the `SELECT_CHALLENGE` response for
`PASSWORD`, `PASSWORD_SRP`, and `WEB_AUTHN`:

* `"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": {
  "ANSWER": "WEB_AUTHN", "USERNAME": "[username]", "CREDENTIAL":
  "[AuthenticationResponseJSON]"}`

  See [ AuthenticationResponseJSON][1].

* `"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": {
  "ANSWER": "PASSWORD", "USERNAME": "[username]", "PASSWORD":
  "[password]"}`

* `"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": {
  "ANSWER": "PASSWORD_SRP", "USERNAME": "[username]", "SRP_A":
  "[SRP_A]"}`

For `SMS_OTP` and `EMAIL_OTP`, respond with the username and answer.
Your user pool will send a code for the user to submit in the next
challenge response.

* `"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": {
  "ANSWER": "SMS_OTP", "USERNAME": "[username]"}`

* `"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": {
  "ANSWER": "EMAIL_OTP", "USERNAME": "[username]"}`

WEB_AUTHN

: ‘“ChallengeName”: “WEB_AUTHN”, “ChallengeResponses”: { “USERNAME”:

"[username]", "CREDENTIAL": "[AuthenticationResponseJSON]"}`

See [ AuthenticationResponseJSON][1].

PASSWORD

: ‘“ChallengeName”: “PASSWORD”, “ChallengeResponses”: { “USERNAME”:

"[username]", "PASSWORD": "[password]"}`

PASSWORD_SRP

: ‘“ChallengeName”: “PASSWORD_SRP”, “ChallengeResponses”: {

"USERNAME": "[username]", "SRP_A": "[SRP_A]"}`

SMS_OTP

: ‘“ChallengeName”: “SMS_OTP”, “ChallengeResponses”: {“SMS_OTP_CODE”:

"[code]", "USERNAME": "[username]"}`

EMAIL_OTP

: ‘“ChallengeName”: “EMAIL_OTP”, “ChallengeResponses”:

{"EMAIL_OTP_CODE": "[code]", "USERNAME": "[username]"}`

SMS_MFA

: ‘“ChallengeName”: “SMS_MFA”, “ChallengeResponses”: {“SMS_MFA_CODE”:

"[code]", "USERNAME": "[username]"}`

PASSWORD_VERIFIER

: This challenge response is part of the SRP flow. Amazon Cognito

requires that your application respond to this challenge within a
few seconds. When the response time exceeds this period, your user
pool returns a `NotAuthorizedException` error.

`"ChallengeName": "PASSWORD_VERIFIER", "ChallengeResponses":
{"PASSWORD_CLAIM_SIGNATURE": "[claim_signature]",
"PASSWORD_CLAIM_SECRET_BLOCK": "[secret_block]", "TIMESTAMP":
[timestamp], "USERNAME": "[username]"}`

CUSTOM_CHALLENGE

: ‘“ChallengeName”: “CUSTOM_CHALLENGE”, “ChallengeResponses”:

{"USERNAME": "[username]", "ANSWER": "[challenge_answer]"}`

NEW_PASSWORD_REQUIRED

: ‘“ChallengeName”: “NEW_PASSWORD_REQUIRED”, “ChallengeResponses”:

{"NEW_PASSWORD": "[new_password]", "USERNAME": "[username]"}`

To set any required attributes that `InitiateAuth` returned in an
`requiredAttributes` parameter, add
`"userAttributes.[attribute_name]": "[attribute_value]"`. This
parameter can also set values for writable attributes that aren't
required by your user pool.

<note markdown="1"> In a `NEW_PASSWORD_REQUIRED` challenge response, you can't modify a
required attribute that already has a value. In
`AdminRespondToAuthChallenge` or `RespondToAuthChallenge`, set a
value for any keys that Amazon Cognito returned in the
`requiredAttributes` parameter, then use the
`AdminUpdateUserAttributes` or `UpdateUserAttributes` API operation
to modify the value of any additional attributes.

 </note>

SOFTWARE_TOKEN_MFA

: ‘“ChallengeName”: “SOFTWARE_TOKEN_MFA”, “ChallengeResponses”:

{"USERNAME": "[username]", "SOFTWARE_TOKEN_MFA_CODE":
[authenticator_code]}`

DEVICE_SRP_AUTH

: ‘“ChallengeName”: “DEVICE_SRP_AUTH”, “ChallengeResponses”:

{"USERNAME": "[username]", "DEVICE_KEY": "[device_key]", "SRP_A":
"[srp_a]"}`

DEVICE_PASSWORD_VERIFIER

: ‘“ChallengeName”: “DEVICE_PASSWORD_VERIFIER”, “ChallengeResponses”:

{"DEVICE_KEY": "[device_key]", "PASSWORD_CLAIM_SIGNATURE":
"[claim_signature]", "PASSWORD_CLAIM_SECRET_BLOCK":
"[secret_block]", "TIMESTAMP": [timestamp], "USERNAME":
"[username]"}`

MFA_SETUP

: ‘“ChallengeName”: “MFA_SETUP”, “ChallengeResponses”: {“USERNAME”:

"[username]"}, "SESSION": "[Session ID from VerifySoftwareToken]"`

SELECT_MFA_TYPE

: ‘“ChallengeName”: “SELECT_MFA_TYPE”, “ChallengeResponses”:

{"USERNAME": "[username]", "ANSWER":
"[SMS_MFA|EMAIL_MFA|SOFTWARE_TOKEN_MFA]"}`
