What if i forget to delete some old accounts associated with the google email address? Will someone be able to take control of them? And my data will be there forever too.
What method do you use to find the old accounts to delete? Unfortunately i delete all emails after receiving them.
To not rely on it anymore? Not be tempted?
I suggest to delete it but giving yourself a grace period, e.g 1 year where you redirect emails until you are sure you updates most people and services accordingly. After that period, better to delete and this way hope that Google doesn’t have any of your data anymore.
