Find out if you have been breached

Data breaches are common occurrences these days. It’s possible and perhaps likely that one of your accounts has been compromised. But how would you know if that’s the case? Often, the service in question will send you an official notice disclosing the breach. You can also use sites like BreachAlarm, LifeLock or Have I Been Pwned to see if you need to change your password due to a breach affecting your account(s).
