One of the most important steps you can take to protect yourself online is to use a unique, strong password for every one of your accounts and apps. Unfortunately, it is most likely impossible for you to remember all your different passwords for all your different accounts. This is why so many people reuse the same password. Unfortunately, reusing the same password for different accounts is dangerous, because once someone compromises your password, they can access all your accounts that use the same password. A simple solution is to use a password manager, sometimes called a password vault. These are programs that securely store all your passwords, making it easy to have a different password for each account. Password managers make this simple, because instead of having to remember all your passwords, you only have to remember the master password to your password manager.
