Smartphone users are being urged to take immediate action to protect their devices from hackers, as experts warn that no system is completely immune to cyberattacks. With banking details, private messages, and photos stored on phones, they have become prime targets for cybercriminals.
Which? has recommended enabling two-factor authentication (2FA) on as many online accounts as possible. This security measure sends a time-sensitive code to your smartphone when you attempt to log in from a new device, adding an extra layer of protection. To activate 2FA, users should navigate to their account security settings, enter their mobile number, and confirm the setup with the code received.
Beyond 2FA, users are advised to remain cautious of suspicious links, avoid unsecured public Wi-Fi networks, and only download trusted apps. Keeping software up to date ensures access to the latest security patches, while habits such as using strong passwords, reviewing app permissions, and locking the device when not in use can significantly reduce risk.
