Which statement about login credentials on public networks is true?

• A. Credentials are never at risk on public networks.
• B. Public networks automatically encrypt passwords.
• C. Credentials might be intercepted if connections are not encrypted.
• D. Using public networks eliminates need for passwords.

Answer: (C)

On public networks, what you send can be exposed to others if it isn’t protected, because the traffic travels through the air and can be captured by anyone on the same network. That’s why the statement about credentials being at risk if connections aren’t encrypted is correct. If you’re using secure connections—like HTTPS with TLS—the credentials are encrypted in transit, so interception is much less likely. But on open networks, non-encrypted or poorly encrypted traffic can be read, so it’s wise to prefer encrypted sites, use a VPN or other protections, and enable strong authentication methods to stay safe.
