A password manager is a software application designed to store and manage your passwords securely. It helps users create strong, unique passwords for different accounts, reducing the risk of using easily guessable passwords. By encrypting your password data, it ensures that only you can access your information. Most password managers also offer features like auto-filling login forms and generating random passwords. This makes it easier to log into websites and services without having to remember every password. Popular examples of password managers include LastPass, 1Password, and Dashlane.
