When you buy an iPhone, you’re trusting that the company that made it has put in the best possible security measures. But how do you know if your data is safe? There are a few ways to verify the integrity of your data on an iPhone: by checking for viruses and malware, verifying that your phone is up to date with Apple’s security patches, and verifying that your phone’s battery is healthy. If you don’t have any of these tools or if they’re not available to you, there are a few other ways to check for integrity on an iPhone. One way is to use a third-party app like Passcode Lock or Face ID. Another way is to use Apple’s own security features, like two-factor authentication or secure sockets layer (SSL) encryption.
