Also, disable Bluetooth if you don’t absolutely need it. By the way, public USB ports are also a way to give hackers access to a smartphone. Therefore, you should always use your own adapter to charge your phone.

Only install trusted apps

Another gateway is your cell phone number. You should not carelessly give them to apps. After all, you do not reveal them to everyone who asks for them. The cell phone number can be used for hacking attacks via SMS, for example. Apps are a touchy subject anyway. Only apps from the App Store can be downloaded to an iPhone – at least without a jailbreak – and those have usually been reviewed by Apple. It’s different with Android smartphones, on which apps can be installed from sources other than the Google Play Store.

Use two-factor authentication

Even if it is annoying – the two-factor authentication (2FA) has its justification. It provides an additional way to protect your phone from hacker attacks. It is well known that most people do not put much effort into creating passwords, which are therefore often easy to crack. Therefore, two-factor authentication is definitely a useful invention. Speaking of passwords: It should be known by now that the name of the dog, one’s own date of birth or the number sequence 12345 are not really suitable for this purpose. Secure passwords consist of 16 to 20 characters and are a combination of letters and numbers, upper and lower case letters and special characters.

Switch on the integrated device protection

Smartphones are not called that for nothing. Their smart features are useful even if the cell phone is lost or stolen. Many devices can be tracked and thus recovered.
