I was wondering how I could make this application where it’s basically the account section in settings. I wanna make this app based on that already existing feature. I’m just not sure if that is available on a custom ROM I’m interested in installing once I fix up my pixel.

I’ve read a bit, not all, but a bit about the Android Keystore System, of which I’m not sure if this is how I can achieve such success.

Storing the credentials in the app, the app then saving it in keystore and when the user goes to their default browser, it then automatically signs them in as per keystore.

I’m not sure if this is how it all works, just clarification. Thanks!
