Locking your iOS device with a passcode can offer some protection for personal data. What if you could password protect photos, or prevent access to any individual app? Now on a jailbroken device with the tweak Password Protect you can add this functionality to iOS for free. Once installed from the Cydia app store, Password Protect adds several photo and application protection options to the Settings.
Not only can you prevent someone from viewing your photos, you can prevent photo access from software besides the Photos and Camera apps. Beyond photos, navigating to Application Protection makes it possible to select one or more apps from a list of those installed. Any apps with protection ON will require a password to launch.
There are other tweaks that can add app and photo protection to iOS, however Protect Photos is completely free. For those who are tired of entering a passcode every time the iPhone is unlocked, Protect Photos offers an alternative that will restrict access to only the most important apps with personal or sensitive information inside.
Protect Photos is available on Cydia from the BigBoss repository for free. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
