anon626 When I sign out, what will happen to my current apps?
I haven't switched google accounts on my phone before I'm 98% sure you're fine.
All of the apps will stay. On your throwaway, you don't have: synced contacts, calendar, or paid apps so you're fine there. Maybe it won't let you sign out of every account. You could do that or sign into both at the same time then get rid of the other--whatever you prefer.
Both accounts will probably be linked by being connected to the same vpn-endpoint or home/work internet + any other metadata. It's a lot easier to de-anonymize data than people think. Could just take knowing 4 or all of the apps on your phone to identify you or know the 2 google accounts are for the same person whoever you are for example.
