In terms of identity crimes, which of the following actions would be considered illegal?

Using someone else’s personal identifiers without permission is considered illegal because it constitutes identity theft or identity fraud. This illicit action involves taking another person's sensitive information—such as their name, Social Security number, or financial account details—with the intent to impersonate them for financial gain or other fraudulent purposes. Laws are in place to protect individuals from such violations, as unauthorized use of personal identifiers can lead to significant harm, both financially and emotionally, to the victim.

In contrast, creating a password is a common security practice that does not violate any laws. Identifying yourself online, when done truthfully and lawfully, is also acceptable. Accessing personal identification for verification, provided it is done legally and with the appropriate consent or authority, is a normal part of many legitimate processes.
