Apple is famous for setting high standards for privacy and data security for its users, but iPhones aren’t protected from hackers. It’s feasible for criminals to obtain sensitive information from numerous iPhone applications that collect it every day — such as browsing history, personal pictures as well as current location and passwords.
The simplest way to protect your iPhone against malicious apps is by ensuring that you use a secure passcodeone that you actually remember and not write down somewhere (you should be doing this already). Another option is to disable the ability to display notification content on the lock screen which will prevent strangers from accessing your personal information without unlocking your phone.
If you want to go a step farther then you can use the Screen Time feature to create a custom alphanumeric passcode, or deactivate access to your 4-digit numeric passcode. This makes it harder for a criminal to brute force your passcode. You can also turn on the feature that erases all information from your iPhone after 10 unsuccessful passcode attempts. This makes your iPhone unusable to thieves, however, it could still be inaccessible to you if aren’t able to access iCloud photos or other content.
Also, you should consider installing a trusted mobile security application, such as Clario. It will alert you to harmful websites as well as protect your personal information from stealing on Instagram and other social networks, block annoying ads and potentially dangerous ones, improve your privacy using the VPN and more.
