Secure Folder is a handy piece of software developed and released by Samsung and it handles the task of protecting user-defined folders on Android devices. This job is achieved by using encryption and sandboxing to take advantage of multiple layers of security and protection. Its user interface comes with a modern and friendly design where you can start protecting files and applications.
In case you want to protect your WhatsApp and other apps that contain sensitive data, you can add them to your Secure Folder and even configure an additional layer of security containing passwords, patterns, PIN and biometric lock. This fancy software can be used to secure contacts, apps, video games, photos, videos, and other types of data on your smartphone.
The data you place inside Secure Folder can't be accessed outside of it and it's not recommended to attempt any rooting or custom ROMs, because you will lose this important data that belongs to you. The nice thing about this tool is that you can change its name and even icon. Everything is based on your Samsung account and you are allowed to back up the data locked inside Secure Folder and later restore it.
