How can I modify the default refresh token duration in Amplify Auth?

You either can modify the "userpoolClientRefreshTokenValidity" parameter in cli-inputs.json file and perform an amplify push operation or you can use the modify properties via overrides on the individual user pool clients to update the same.

Please refer to the below GitHub Discussion for detailed information :

• https://github.com/aws-amplify/amplify-cli/issues/13293

Kindly note that the "userpoolClientRefreshTokenValidity" parameter is depended on the "RefreshTokenValidity" parameter used to specify the time units such as seconds, minutes, hours or days. By default, Refresh token has days unit. Hence, to change the units, you might have to explore the overrides method to update the same.

You may also refer to the below documentation for reference on the same :

• https://docs.amplify.aws/javascript/tools/cli/reference/files/#cli-inputsjson
• https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_TokenValidityUnitsType.html
• https://awscli.amazonaws.com/v2/documentation/api/latest/reference/cognito-idp/create-user-pool-client.html
