    I’m just using Mozilla’s Multi-Account Containers extension. In my work’s infinite wisdom I have a total of five “single sign on” accounts. So I have different containers for each account so I avoid the endless “which account would you like to use” and “this account doesn’t have access to this resource”.

    The extension allows me to set specific domains to always open in container X. That covers 90℅ of my use cases. Some sites I need to use different accounts with and for that I have to select which one to use each time.












  • It’s mostly a power efficiency thing. Before push notifications were the norm, most apps used a polling method. They had the application send a request every X seconds asking “anything new”. There wasn’t coordination between apps, so even every app checked once every 30s, it likely wouldn’t be on the same 30s. This caused the device to wake up a lot and never let it switch into low power mode.

    A push notifications system like FCM or UnifiedPush means only a single application needs to run in the background. It maintains a persistent connection to the push notification service and waits for a message. When it receives one it wakes up the relevant app and passes it the details.





  • The issue lies with Google’s FCM (Firebase Cloud Messaging) system, so it’s not something GrapheneOS can really fix. As far as I know FCM doesn’t offer a way to encrypt notification content. Some apps like Signal work around this by instead of sending the message content, they send a little “wake up” notification. This tells Signal on your phone to wake up and it goes and retrieves the new message.

    If you don’t install Google Play Services, you won’t be impacted. But you’ll also not get notifications for most applications. There is an alternative push notification system called UnifiedPush which allows you to choose any server to handle your notifications (and even self host it). But it does require both the service and the app to support it, so it’s not very wide spread yet.



  • Yes it’s possible. From my very basic understanding of it there’s two ways Google can verify devices, using software or dedicated hardware. As long as Google continues to accept the software check you can root and still pass. Google can’t reject the software results without cutting off a large number of older or cheaper phones. There’s no way to get around the hardware check as far as I know.
