Apple is known for setting high standards for privacy of its users and data security, but iPhones aren’t secure from hackers. It’s possible for criminals access sensitive information through the numerous iPhone applications that collect it on a daily basis — including browsing history, personal photographs as well as current location and passwords.
The easiest way to secure your iPhone against apps is by ensuring that you have a strong passwordone that you remember and not note down anywhere (you should be doing this anyway). Turning off the notification content on your lock screen can prevent strangers from accessing your private information without unlocking the phone.
If you’d like to take it further then you can use the Screen Time feature to create a unique alphanumeric passcode or deactivate access to your 4-digit numeric passcode. This will make it more difficult for a criminal to brute through your passcode. You can also set the feature that will erase all data stored on your iPhone after 10 incorrect passcode attempts, which will render your device unusable to thieves, but it could be useless for you as well if you’re not able access your iCloud pictures or other content.
Also, you should consider installing a trusted mobile security app like Clario. It can alert you of unsafe websites, protect your identity from theft on Instagram and other social media, stop annoying and potentially harmful advertisements, improve your privacy by using VPN, increase your privacy with VPN and much more.
