  • Adding a rootCA cert to system store

Hello,

I am using GrapheneOS for a long time now. I want to install a CA Certificate on system level, to a.e. force bitwarden to use mTLS with my home server setup.
Is there any way to do this on GrapheneOS, since there is no root level access to the file system?

Thank you in advance!

You can install a user certificate as you would on any other Android OS.

    flawedworld Thanks for your awnser. That is not enough. Android has 2 different types of Trust Stores, the user trust store and the system trust store. I need to add a certificate in the System Trust Store for my use case.
    Else the Bitwarden app (just as example) won't use my Cert. Since the App manifest defines to only trust the System store.
    Or am I wrong here? oO

    It is an app issue if the app forbids using the user trust store.

      Swab8184 So its not possible?

      I think the productive thing is probably to ask the app author how to get the app to accept a user-store cert.

      That is, assuming that has been tried and did not work.
