9. Set Up a BIOS or UEFI Password
Your laptop’s BIOS or UEFI is the firmware responsible for booting up the system. Setting a password for this can prevent unauthorized users from starting your laptop or making changes to its core settings.
Actionable Tip: Access your laptop’s BIOS/UEFI settings during startup (usually by pressing a specific key like F2 or DEL). Set a strong, unique password and store it securely in case you need to recover it.
10. Opt for Biometrics for Login (Fingerprint, Face ID)
Biometric security, such as fingerprint scanning or facial recognition, is becoming increasingly common and offers enhanced security compared to traditional passwords. These features make it much harder for anyone other than you to access your laptop.
Actionable Tip: If your laptop supports it, enable biometric login options like fingerprint scanners or facial recognition through the settings menu. These methods are not only secure but also more convenient.
In a world where data breaches and cyberattacks are becoming all too common, ensuring that your laptop and personal information are safe should be a top priority. By following these 10 best practices, you can significantly reduce the risk of being targeted by cybercriminals. Start implementing these strategies today, and make sure your laptop remains a secure haven for all your data.
