I will build an app that will have 2 Features
- Store a unique secret that will never leave the Device
- Store a secret that has to be backed up
For the first Feature, I would choose the following native API’s
- Android: Keystore
- iOs: Secure Enclave
For the second Feature, I would choose the following
- Android: KeyValue Backup
- iOs: Keychain Services
Now when I look at the Documentation of Expo’s [SecureStore] I can see, that they use Keychain Services for iOs and the Keystore for Android. This is a Problem for me, because for my features I need to differentiate between a store that is backed up and a store that will never leave the device.
So my questions are:
Did I pick my native API’s wrong, or missunderstood something?
Is there another Expo API I can use or does Expo simply not support what I need?
(As I am a new user in this forum I can only have 2 Links in my post. I have also posted the same question on StackOverflow with links to the native apis )
