Samsung has one of the most efficient operating systems, and it is packed with features to meet the expectations of its users. Samsung’s older mobile phones had an app lock feature in the security section, which was later changed to the Secure Folder feature. However, if you have an old Samsung phone, you can still use that feature by going to settings> security option> enable app lock and choose your lock settings, select the apps you want to lock and you’re done.

But, if you have a phone running Android 7.0 or later, you will have access to the Secure Folder feature, which you can use to protect your private data in apps, but it may be difficult to set up. To easily set up Secure Folder, follow the steps outlined below.

  • Navigate to your Phone’s settings.
  • Select Lock Screen and Security.
  • Tap on Secure Folder.
  • It might prompt you to sign in to your Samsung Account.
  • Simply enter your account information and log in.
  • Then, select the type of lock screen you want and press the next button.
  • Set the lock as you want.

  • If you want to add an app, tap the plus icon at the top, which will display all of the apps on your phone.
  • Choose the apps you want to secure.

How Does It Work?

When you add an app to this folder, it creates a secure copy of that app that functions as an individual app. You can delete the original app after adding it to Secure Folder, and it will not affect the app in the folder. The most important thing to remember is that if you add WhatsApp to the Secure Folder, it will act as if you installed it from the Play Store and it will have no data, so you will have to set it up again. The original one can be deleted outside the app after you set it up.
