> you generate What do you mean by this? Because if by "you" you mean a closed source program which is automatically updated generates it for you on your device then I think it's more accurate to say "Service X generates it". As an example consider Ethereum. It's supposedly decentralized, but when someone stole a lot of money from the founder's friends, he unilaterally changed the blockchain by pushing a software update to almost everyone. If the keys are created, stored, and controlled by Google on your device, you don't actually own the keys, Google does. You're just renting your phone to Google.
