The Screen Time password has been long recommended as an extra security layer. By setting a Screen Time password without any additional restrictions, Apple users could easily dodge attempts of changing or removing the screen lock passcode, resetting the iTunes backup password, or removing the activation lock. For a long time, removing the Screen Time password was not possible without either providing the original password or erasing the device. However, Apple had changed the way it works, making it possible to reset the Screen Time password with an iCloud/Apple ID password.

Everyone’s iPhones contain overwhelming amounts of highly sensitive personal information. Even if some of that data is not stored on the device, the iPhone itself or the data inside can work as a key to other many things from bank accounts to private family life. While there are many possible vectors of attack, the attacker will always try exploiting the weakest link. Learn to think like one, find the weakest link and eliminate the potential vulnerabilities before they are exploited. This guide comes from the forensic guys making tools for the law enforcement, helping the good guys break into the bad guys’ iPhones.

The iOS backup system is truly unrivalled. The highly comprehensive, versatile and secure backups can be created with Apple iTunes. For the user, local backups are a convenient and easy way to transfer data to a new device or restore an existing one after a factory reset. For forensic experts, iOS backups are an equally convenient, versatile and easy way to obtain a copy of the user’s data without attempting to break into the device. In malicious hands, the backup becomes a dangerous weapon. Logins and passwords from the Keychain allow hackers accessing the user’s social accounts, messages, and financial information. A backup password can be set to protect local backups, but it can be removed just as easily shall the hacker have access to the physical iPhone and know its passcode. In this article, we’ll discuss how the Screen Time password can be used to further strengthen the protection of local backups.

For us, this year has been extremely replete with all sorts of developments in desktop, mobile and cloud forensics. We are proud with our achievements and want to share with you. Let’s have a quick look at what we’ve achieved in the year 2019.

Passwords are probably the oldest authentication method. Despite their age, passwords remain the most popular authentication method in today’s digital age. Compared to other authentication mechanisms, they have many tangible benefits. They can be as complex or as easy to remember as needed; they can be easy to use and secure at the same time (if used properly).

The Screen Time passcode is an optional feature of iOS 12 and 13 that can be used to secure the Content & Privacy Restrictions. Once the password is set, iOS will prompt for the Screen Time passcode if an expert attempts to reset the device backup password (iTunes backup password) in addition to the screen lock passcode. As a result, experts will require two passcodes in order to reset the backup password: the device screen lock passcode and the Screen Time passcode. Since the 4-digit Screen Time passcode is separate to the device lock passcode (the one that is used when locking and unlocking the device), it becomes an extra security layer effectively blocking logical acquisition attempts.

The Screen Time passcode (known as the Restrictions passcode in previous versions of iOS) is a separate 4-digit passcode designed to secure changes to the device settings and the user’s Apple ID account and to enforce the Content & Privacy Restrictions. You can add the Screen Time passcode when activating Screen Time on a child’s device or if you want to add an extra layer of security to your own device.
