(2) (A) Disclose and deliver the required information to a consumer free of charge, or correct inaccurate personal information, or delete a consumer's personal information, based on the consumer's request, within 45 days of receiving a verifiable consumer request from the consumer. The business shall promptly take steps to determine whether the request is a verifiable consumer request, but this shall not extend the business's duty to disclose and deliver the information, or correct inaccurate personal information or delete personal information, within 45 days of receipt of the consumer's request. The time period to provide the required information, or to correct inaccurate personal information or delete personal information, may be extended once by an additional 45 days when reasonably necessary, provided the consumer is provided notice of the extension within the first 45-day period. The disclosure of the required information shall be made In writing and delivered through the consumer's account with the business, if the consumer maintains an account with the business, or by mail or electronically at the consumer's option if the consumer does not maintain an account with the business, in a readily useable format that allows the consumer to transmit this information from one entity to another entity without hindrance. The business may require authentication of the consumer that is reasonable in light of the nature of the personal information requested, but shall not require the consumer to create an account with the business In order to make a verifiable consumer request, provided that if the consumer has an account with the business, the business may require the consumer to use that account to submit a verifiable consumer request.
