A lot of us do it: We repeat the same password for every single account we make, or at least some variation of that password. It's the most convenient option so you don't need to remember dozens of passwords at once — but it can be risky. If a hacker gains access to your main passwords, they can then get access to far more than just one account of yours. Use the same password for important accounts like your Amazon account or online banking, and you're in trouble. That's where a password manager comes in, and most antivirus software packages thankfully include them. A password manager stores all of your passwords in one place, saving you the need to remember them all. They even create strong ones for you, which makes it much harder for someone to access all your accounts (and protects you in case of data leaks by firms).
