Hi, I checked the account history quickly, and saw the hack had nothing to do with your account email. The attacker used the reset password function and got the right reset key right after, which he used to change your password. Therefore here are my questions for you:

• Was your email password strong too?
• Are you sure you NEVER logged into your email from any other place than your home, on a safe computer (ie. never used that email from a mobile device, for example)
