Question

What is the most vulnerable information that should be protected to prevent unauthorized access to your online files and records?

Answer 1

Answer:

Your user ID and password.

Explanation:

The user Id and password must be protected because when it is exposed to a third party then they can get access to information, data, to things they are not supposed to.

The user Id and password is provided as an authentication measure for one to be able to gain access to a computer system, network or files. It is what grants access to online files and record as it is the case here. It has to be protected for the sake of privacy.
