Hi,

I have set up a "Secure Folder" for use with work. However, my company requires that I install a custom CA certificate in order to access our internal systems.

I found out how to install a CA certificate in my normal profile by following these steps:

However, I can't find out how to install it inside "Secure Folder".

Can someone let me know how I can do this?

Figured out how to do it.

The main issue is, Android 11 now forces you to install CA certificates in "Settings" only, not through an app. However, as of writing this post, there's no way to bring up the normal "Settings" menu inside "Secure Folder".

The solution is to download an app called "Hidden Settings" from the app store. If you run it from inside "Secure Folder", the first item in "Hidden Settings" will bring up the main "Settings" menu for "Secure Folder" which you can then install your custom certificate.

If this works then you are a savior. I tried to do this 2 years ago and gave up. Hope the app is safe though. Being inside secure folder would be bad if malicious.

The app doesn't ask for any permissions, and it's in the app store for a long time, I feel it's safe. All we need from it is to launch the "Settings" menu that's built into our phone. The app itself isn't doing the certificate install.

Also, 2 years ago Android didn't require you to install certificates through "Settings", you could have just downloaded the certificate on your phone then open it using Samsung's "My Files" app, and it will install it. This problem only started in Android 11, which was released in September 2020.
