The majority of people use very weak passwords and reuse them on different websites.
Password managers store your login information for all the websites you use and help you log into them automatically.
They encrypt your password database with a master password – the master password is the only one you have to remember.
To prevent password leaks from being so damaging, you need to use unique passwords on every website.
These should also be strong passwords – long, unpredictable passwords that contain numbers and symbols.
Web geeks have hundreds of accounts to keep track of, while even the average person likely has tens of different passwords.

Remembering such strong passwords is nearly impossible without resorting to some sort of trick. The ideal trick is a password manager that generates secure, random passwords for you and remembers them so you don’t have to.

KeePass is a free and open-source popular desktop application for managing your passwords, but there are also browser extensions and mobile apps for KeePass. KeePass stores your passwords on your computer so you remain in control of them — it’s even open-source, so you could audit its code if you wanted to. The downside is that you’re responsible for your passwords, and you’ll have to sync them between your devices manually. Some people use a syncing solution like Dropbox to sync the KeePass database between their devices.
