You should always use a password manager of some kind. Why? Because you shouldn’t use the same password on multiple websites or for multiple applications. If you do, a hacker can get into all of your accounts after breaking into only one of them. The same thing goes for PIN numbers and bank accounts.
Your password manager can be installed as a web browser extension, as a portable application on a USB flash drive or even something much simpler. As long as you are the only person who can get into your password manager, you’re about as secure as you can get.
I won’t get into the specifics of each password manager I know about. Here’s a list of links:
If you search for them online, you’ll find even more. Some of these products work online and some only work on the local machine. Some work with all devices and some work with only one. You owe it to yourself to investigate each one.
The things I didn’t include on the list are things done the “old school” way. Way back when, way before any password manager existed, I kept my passwords in a little address book made of paper. Just like those guys in the 1990 Ghost movie. Then I graduated to a computer text file. I started using LastPass shortly after it became available.
Good luck because I can’t tell you which one is best for your specific situation. If you only need to remember a few, and you can memorize them, your memory is the best password manager. Otherwise, you should always use a password manager secured with a master password. That way, you don’t have to remember the other passwords.
Your master password should be complex, yet easy to remember. No one, not even your closest family member, should be able to guess it. Every password should be a strong password, even if you’re using it for a homegrown CMS on a local computer. Creating strong passwords should become second nature to you.
