There are said to be people who find unlocking their cell phones too difficult and therefore simply do not activate this security function. For the other faction, Apple is now providing a new security barrier with version 17.3 of the iOS operating system. It makes it harder to unlock an iPhone without authorization and steal data. For example, thieves in clubs, restaurants or other public places. Most iPhones are secured using biometric methods, facial recognition on the newer devices, and a fingerprint sensor on the older ones. But there is also an additional code that serves as an easy-to-use fallback option if the biometric unlocking methods don’t work.
