Over 90% of the population now owns a smartphone according to the latest digital barometer 2026 from Arcep. Even though only 79% of retirees use one, the device has become almost essential in daily life. However, its use requires a minimum of security to protect the valuable data it contains, as there is often “our whole life” in those few square centimeters of technology.
Fortunately, some simple habits can reduce the risk of hacking or fraud. “With the increase in online scams and increasingly sophisticated threats, users must remain vigilant,” said Vincent Ollivier, spokesperson for cybersecurity expert Bitdefender. “The goal is not to become a cybersecurity expert, but to adopt some basic practices that offer effective daily protection.”
Code PIN and Biometrics: Lock Your Mobile Access Efficiently
To secure physical access to your smartphone, the first step is to configure a longer PIN code. You can switch from 4 to 6 digits in the security and privacy settings of your device. Depending on the model of smartphone you own, you will also find in the settings how to activate biometric authentication, i.e., fingerprint recognition or facial recognition. Very practical and secure for unlocking the phone.
Updates and Official Stores: Avoid Fraudulent Applications
It is essential to keep your phone system and applications up to date, as these patches regularly close important security vulnerabilities. Moreover, to avoid downloading malicious or fraudulent applications, always limit yourself to official stores accessible from your device such as the Apple App Store on iPhone or the Google Play Store for Android phones.
Password Manager: Secure Each of Your Online Accounts
Just like on a computer, it is much safer to use different passwords for each of your services. To simplify your life and not forget anything, a reliable password manager can take care of creating and securely storing all your passwords.
Application Permissions: Protect Your Privacy and Data
Many applications request access to your location, microphone, photos, or contacts. Take the time to check these permissions in your settings and take the opportunity to permanently delete apps you no longer use.
Location and Remote Wiping: Anticipate Loss or Theft
By enabling location and remote wiping functions, you will be able to locate your phone if you misplace it. In case of theft, this option will allow you to remotely erase all your data to ensure it does not fall into the wrong hands.
