3. Password-Protect Your Device
For mobile phone users, more than three out of four respondents said they password-protect their phones, according to Varonis. Most mobile devices support either using a password to gain access or a pin code. The developers behind Android are experimenting with other protections, including facial recognition and password-swipe functionality, but security experts say a pin code is the most reliable way to keep the device secure. A standard password is less convenient but offers more protection.
