It's a good thing that you got your assets back, but be careful next time, there's lot of news nowadays that their wallet is being hacked, the easiest and well-known type of hacking is phishing, many people click some links that can gather all their info, maybe you use your account in online stores since you are in the US, maybe you buy on Amazon and you linked it with your credit card or your PayPal in which you have your full info and that info can be used to open your account. I used google authenticator and sms verification too the phone that I am using doesn't have any apps just email and authenticator for me to prevent hacking.
