I've noticed that I have made mutliple aliases and gmail accounts and I've checked them most of them are missing messages. I've even enabled 2fa for most of my gmail accounts and noticed the something or an app got access to my accounts and started eating away some of my mail (even for the accounts with second factor authentication installed). I've started a gmail deleted email recovery process for some of my accounts as well but that didn't do much. I did not have or create a back up prior to these lost emails. If my account was compromised in the beginning, how can I ensure it won't get compromised again? I didn't share my passwords with anyone, and I am the only one that knows and had access to these email accounts. What can I do to ensure this doesn't happen again?
