Here are some limitations on the types of data that should not be stored in cookies:
Sensitive Personal Information: Cookies should not contain sensitive personal information such as passwords, social security numbers, or financial data. Storing such data in cookies can pose a risk of abuse and compromise user privacy.
Credit Cards and Financial Data: Information about credit cards and other financial data should also remain outside of cookies due to the risk of leaking these confidential details.
Medical Information: Data about health status or other medical information is highly sensitive and should be handled with special attention to privacy.
Passport Data and Social Security Numbers: Passport data and social security numbers are unique identifiers that can be used for identity theft. Storing such data in cookies can be potentially dangerous.
