No matter how secure and strong your password is you account will get hacked if you been a victim of phishing/keylogger/backdoor.
Brute forcing is quite outdated as a matter of fact unless you are using plain text/ default passwords like: Password123, admin, johnlovemarry, shane etc so its better to read and keep yourself updated regarding the new techniques and methods and prior to that using an anti virus is must. Being a security expert i strongly recommend bitdefender and malwarebytes pro.
