The number of previous passwords that you want Amazon Cognito to restrict each user from reusing. Users can't set a password that matches any of n previous passwords, where n is the value of PasswordHistorySize . Password history isn't enforced and isn't displayed in DescribeUserPool responses when you set this value to 0 or don't provide it. To activate this setting, advanced security features must be active in your user pool.
