associate_software_token#

CognitoIdentityProvider.Client.associate_software_token(**kwargs)#

Begins setup of time-based one-time password (TOTP) multi-factor authentication (MFA) for a user, with a unique private key that Amazon Cognito generates and returns in the API response. You can authorize an AssociateSoftwareToken request with either the user’s access token, or a session string from a challenge response that you received from Amazon Cognito.

Note

Amazon Cognito disassociates an existing software token when you verify the new token in a VerifySoftwareToken API request. If you don’t verify the software token and your user pool doesn’t require MFA, the user can then authenticate with user name and password credentials alone. If your user pool requires TOTP MFA, Amazon Cognito generates an MFA_SETUP or SOFTWARE_TOKEN_SETUP challenge each time your user signs in. Complete setup with AssociateSoftwareToken and VerifySoftwareToken.

After you set up software token MFA for your user, Amazon Cognito generates a SOFTWARE_TOKEN_MFA challenge when they authenticate. Respond to this challenge with your user’s TOTP.

Note

Amazon Cognito doesn’t evaluate Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can’t use IAM credentials to authorize requests, and you can’t grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see Using the Amazon Cognito user pools API and user pool endpoints.

Request Syntax

response = client.associate_software_token(
    AccessToken='string',
    Session='string'
)
Parameters:

  • AccessToken (string) – A valid access token that Amazon Cognito issued to the user whose software token you want to generate.

  • Session (string) – The session that should be passed both ways in challenge-response calls to the service. This allows authentication of the user as part of the MFA setup process.

Return type:

dict

Returns:

Response Syntax

{
    'SecretCode': 'string',
    'Session': 'string'
}

Response Structure

  • (dict) –

    • SecretCode (string) –

      A unique generated shared secret code that is used in the TOTP algorithm to generate a one-time code.

    • Session (string) –

      The session that should be passed both ways in challenge-response calls to the service. This allows authentication of the user as part of the MFA setup process.
