 You get a lot done on the internet. That means you probably have a lot of accounts with tons of websites, right? But do you use the same password on all of them? Or do you almost use the same password and change it a little bit for each site? Well, that's a problem. If you use the same password on every website and just one of these websites gets broken into by cyber criminals and there's always one site you use that's not secure, then those thieves could get ahold of the passwords of everyone on that site. And then they can use them to break into all those other accounts. These kinds of break-ins happen far more often than you think. Sometimes they even happen without the hacked website knowing. So don't reuse your passwords. But wait, if you have lots of website accounts and each of them now needs a unique password, how can you possibly remember them all? Aren't we supposed to keep our passwords in our heads and never write them down? Writing them down isn't actually that bad of an idea. If you use lots of passwords, write them down and keep them somewhere safe, like your wallet, then you'll at least know if your written passwords go missing or get stolen. That's more than you might know if you use just one password everywhere and then a website you use is silently hacked. An even safer plan, though, is to use a password manager. Password managers are programs you can download for your phone or computer. They will create, store and even automatically fill in unique passwords on websites and other online services. They can keep all your account details safe and synchronize them between all your devices, so you never have to remember all those passwords again. You can search for password manager reviews to find out what the most secure net users out there prefer. Use password managers to resist the temptation to use one password on all your sites. Remember, it's a trap. There is one catch with all password managers, though. Password managers do need a password for themselves, one that you type into the manager to unlock all the others. You'll want that password to be extra secure, but easy to remember because it's the one password you won't be able to store in your password manager. But that one password will keep you a lot safer in a sometimes dangerous net.
