a tool that automatically changes your password every day
a second step that adds extra security by requiring additional information like a code
a way to log into two accounts at once

Explanation:

• Question 22:
• Worms are malware.
• They can affect various devices, not just mobile.
• They can cause harm (e.g., by consuming resources).
• The key difference is that worms do not need to attach to other files to spread (unlike viruses which often attach to executables or documents).
• Question 23:
• A Trojan Horse is a type of malware that disguises itself as legitimate software but has malicious intent (e.g., stealing data).
• A web browser is a software for accessing the web (not malware).
• A spreadsheet program is for data analysis (not malware).
• Antivirus software is for protecting against malware (not malware itself).
• Question 24:
• Two - factor authentication (2FA) is a second step.
• It adds security by requiring additional information (e.g., a code sent to a mobile device in addition to a password).
• It is not about changing passwords daily, logging into two accounts at once, or using the same password on two devices.

Answer:

• Question 22: Worms do not need to attach themselves to other files to spread.
• Question 23: Trojan Horse.
• Question 24: A second step that adds extra security by requiring additional information like a code.
