Examples of account compromises are on the rise. Weak passwords are one culprit. Phishing (social engineering) scams are also rampant. Even programs such as key loggers which record the keystrokes you type and then relay the information to a third party who extracts out the resource and credentials are common.
In this day and age, you should do everything you can to protect your credentials and therefore your data. Strong passwords help. Another way, which is becoming more common, is two-factor authentication. This method uses your existing credentials to login, but also requires you click a button or enter a random code from your mobile device to proceed. This mechanism is highly secure and can prevent almost all types of account compromises.
