Apple has implemented a variety of security features over the years to protect user data, such as credit card information and so on. Some of those features include the Apple ID security questions and backup email. Adding a backup email, or "rescue email" as Apple calls it, allows you to reset your security questions, and recieve account security-related notifications.
Apple ID security questions help ensure that you're the only person who can access your own account, but they can be a major problem if you forgot the answers to any of the questions. Luckily you can reset your security questions if you have a "rescue email" setup. If you don't have a rescue email you will need to contact Apple Support for help.
When it comes to iPhone security, you can never be too careful. Considering the amount of personal information – not to mention money – the average iPhone user puts into their device, any additional measures you can take to help make sure that it’s all safe is time well spent.
Blocked makes it possible to enforce more robust security and privacy on iOS devices. Once installed, Activator actions can be configured to enter two different secure modes: Sleep mode and Guest mode. Both modes function in a similar manner, by blocking access to certain apps or settings when enabled. This means you can be sure exactly what's happening on your iOS device when lending it to someone, or when it's time to sleep.
Opening the Control Center or Notification Center from the iOS lock screen is convenient. It can also be viewed as a security risk for those who like their devices locked down. The jailbreak tweak Secret-Lock adds an additional layer of security to prevent unauthorized access to all lock screen features on the iPhone.
Once installed, Secret-Lock can be toggled in the settings. There are some options to be configured, including the secret Activator gesture that will unlock the lock screen. Everything on the lock screen will be inaccessible until this gesture is performed.
