Lock pictures on android4/26/2023 Each of the files within the vault can be opened from within the app. To open a particular vault folder, you need to provide its specific password. Here, we’ve picked a few such apps that fulfil this requirement. So, if you really want to protect your private data, you should instead look for apps that use industry grade encryption algorithms (such as AES 256) to encrypt data on your Android device. But studies have shown that the popular vault app is quite easily crackable as it doesn’t implement a standard encryption algorithm. On the other hand, a few security apps, such as Vault from NQ Mobile Security, claim to encrypt your data with passcode. But as it doesn’t implement encryption, these hidden files could be recovered quite easily, by browsing the device storage using a regular file manager app. Turns out, many of these apps do not actually encrypt the file, leaving them vulnerable, and easily recoverable without the passcode.įor instance, AppLock from DoMobile is one of the most popular app lockers on Google Play, but its app-lock screen can be bypassed in several ways, based on its on-device implementation.Īdditionally, the Vault feature of the app is intended to hide your private photos and videos on your Android device. In our tests, we imported photos and videos into different vault apps, and tried to recover them externally without unlocking them.
