I am not logged into a Google Account on my Graphene phone. When I pair Google Messages to a web browser with QR, I now get a popup that says, "QR pairing is going away soon," and prompts me to sign in with Google.
The reason I liked Google Messages for Web so much is that it's an end-to-end encrypted connection from the Android device to the browser client. If and when QR code pairing gets totally disabled, does anyone have any ideas how to keep messages private from Google servers?
For example, has anyone tried signing into their phone with a burner Google account, using that account to pair Messages for Web in a browser, then signing out of Google on both devices? Do the devices stay paired after signing out?
