Samsung Is Terminating My Knox

In early June 2017, Samsung sent out this email to all registered Samsung users :

My Knox will no longer be available on new Samsung devices in 2017. You may continue your secure space experience by setting up Secure Folder, available now from Galaxy Apps.

Samsung Secure Folder Kills & Replaces My KnoxSecure Folder runs on Android N OS or higher versions only. It leverages the defence-grade Samsung Knox security platform to create a private, encrypted space on your Samsung Galaxy phone. Applications and data moved to Secure Folder are partitioned separately on the device and gain an additional layer of security and privacy.

To seamlessly transfer your private content between solutions, please back up your My Knox data and restore it to Secure Folder. To back up your My Knox data, go to My Knox settings > Backup and restore. Remember, a Samsung account is required to use this feature.

You can restore the backup data after setting up Secure Folder. Go to Secure Folder settings > Backup and restore > Restore.

You may use My Knox until its end-of-service date (which will be announced soon). However, be aware that we will not be actively maintaining the service or adding new features.

This was followed by this email on 15 November 2017, revealing its end-of-service date as 19 December 2017.

Dear customers,

Thank you for using My Knox.

As previously announced, we will end support for My Knox on 19th December 2017. You will not be able to download My Knox from any app store after the end-of-service date.

You may use My Knox on your mobile device until you uninstall the application. However, you will be unable to log in to the My Knox portal to remotely manage your device (e.g. to reset your My Knox password or unlock My Knox).

If you have a phone that runs the Android N OS, we recommend transferring your private data in My Knox to Secure Folder*, available at Google Play or Galaxy Apps, and on new Samsung phones such as the Galaxy Note 8. We also recommend backing up your My Knox data first, and restoring the data after you set up Secure Folder.

To back up My Knox data, go to My Knox Settings > Backup and restore > Back up My Knox data. Please note that a Samsung account is required to use the My Knox backup and restore feature.

If your phone does not support Secure Folder, then please back up the content to outside My Knox (e.g. using the Move to Personal mode feature).

We hope you have enjoyed your experience with My Knox. Samsung is committed to continuous innovation to provide you with the highest-quality products and services.

* The availability of Secure Folder varies, depending on region and carrier, even for N OS devices.


Samsung Secure Folder

Samsung Secure Folder is a new security solution that leverages the defense-grade Samsung Knox security platform to create a private, encrypted space on a Samsung Galaxy smartphone running on Android 7.0 Nougat or better. It is available in the Samsung Galaxy S8 / S8 Plus and Galaxy Note8 smartphones, but can be downloaded and installed in the Samsung Galaxy S7 and Galaxy S7 edge smartphones that have been upgraded to Android 7.0 Nougat.

As no Mobile Device Management (MDM) is required, it is suitable for both personal and business usage. Apps and data can be installed or created within Secure Folder, or moved there from outside. Here are the additional details about Samsung Secure Folder :

  • Apps and data moved to Secure Folder are kept separate, leveraging SE for Android – preventing unauthorized communication between apps inside and outside Secure Folder.
  • Application data and files are encrypted with defense-grade Sensitive Data Protection (SDP) technology – using 256-bit AES cipher algorithm to secure data.
  • Data remains encrypted even after the user has exited Secure Folder or has turned off the device, and is decrypted when a user authenticates to access the Secure Folder. But keep in mind that Secure Folder authentication is just a gatekeeper to the encrypted data.

It can also be used alongside Knox Workspace, enabling two Knox container solutions at the same time. This allows users to have access to both a dedicated work environment (Knox Workspace), as well as a secure personal area (Secure Folder).

    So let’s see. You have MyKnox and put sensitive info in there. And now you trust Samsung to back up your data to the cloud where they or anybody they sell it to can run offline attacks on your data without breaking your device.


    Why isn’t there an option to back up to your own SD card? The SD card is not visible from MyKnox.

    Major fscking screwup. I hope you guys don’t quit your day jobs.

      Backup for Secure Folder is NOT enabled by default. You have to log into Secure Folder and manually enable it.

      Needless to say – backing up sensitive information to the cloud is not a good idea at all.

      From what I understand, that’s because it doesn’t function like “drive” but a container that allows apps to execute from within, as well as using it for file storage.
