Cybersecurity expert Ben Jones, who warns against using short, number-only passwords because they can be instantly cracked by hackers. He recommends creating strong, longer passwords that include a variety of characters, or preferably, a pass-phrase. The expert also suggests using multi-factor authentication, preferably through an authenticator app, and avoiding clicking suspicious email links by typing the address directly into the browser instead. Additional advice includes using a VPN on public Wi-Fi and being careful about sharing personal information online.
