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 the same password across multiple sites. Most password managers encrypt your data, ensuring that only you can access your passwords. In addition to storing passwords, many password managers offer features like password generation, autofill for login forms, and security audits to identify weak or reused passwords. Popular examples of password managers include LastPass, 1Password, and Bitwarden, each providing various tools to enhance your online security.
