What type of information is critical to keep secure?

Bank details and passwords are critical to keep secure because they directly relate to a person's financial identity and access to sensitive accounts. If such information falls into the wrong hands, it can lead to unauthorized transactions, theft of funds, or identity theft. Protecting this information is essential to maintaining the integrity and security of one's financial resources and personal identity.

In contrast, while emails and social media activity may contain personal information that could be used in identity theft scenarios, they don't have the same direct implications for immediate financial loss as bank details and passwords do. Shopping preferences, though possibly of interest to marketers, generally do not pose a significant risk if compromised compared to the severe consequences associated with the exposure of bank information and passwords.
