- Update your passwords at least about every six months.
- If you're one of those who uses the same password across multiple sites, use common sense. Obviously, passwords for banking should absolutely be different and unique. However, if you're an administrator or a moderator on a forum, those passwords should also be unique. Otherwise, if it's just small sites, like here—although, obviously, your license account password should be different—where you're just a member, it's not too big of a deal.
- If you feel you may have fallen for some phishing spam or even just end up on some spam site via a link, even if it turns out be nothing in the latter's case, run scans and then update passwords immediately.
- Use two-step authentication.
Feel free to provide other security tips, and I'll add them to the list. Just thought this might be something fun to do.
