You certainly will always need to change your password, and sometimes more urgently than you think, but mitigating against theft is a great way to stay on top of your account security. You can always head to to check if you’re at risk, but merely thinking your password is secure enough not to be hacked into, is a wrong mindset to have. So, to help you understand how hackers get your passwords – secure or otherwise – we’ve put together a list of the top ten password-cracking techniques used by hackers. Some of the below methods are certainly outdated, but that doesn’t mean they aren’t still being used. Read carefully and learn what to mitigate.
