How to secure your iPhone?
Use the additional security features on your iPhone in case you lose your phone. If your passcode is known, it is easy for someone to remove the Face ID and access your Apple details. To add an extra layer of security, use the screen passcode.
Adding the screen passcode will make it difficult to change your Apple ID details, even if the passcode is known. This adds another layer of security. All you have to do is turn on the “Passcode Changes” option and set it to “Don’t Allow” in Content & Privacy Restrictions. Additionally, set a screen passcode. By doing so, it will be very difficult for anyone to change the Apple ID on your iPhone, even if they know your passcode.
These tips will help you protect your iPhone. Thank you very much.
