How do I protect myself against data breaches?

Large data breaches happen regularly, with emails and passwords being made available on the dark web or just free to hackers. Why is this a problem? Very simply because people often reuse their passwords for different online accounts. This leaves those accounts vulnerable to access by hackers. Tip: Don’t reuse passwords! I realise this can be easier said than done, but it’s the best way of minimizing your exposure in the event that an online service you use is breached.
