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 password-related security breaches. By using a password manager, you only need to remember one master password to access all your stored credentials. Most password managers also offer features like password generation, autofill for login forms, and secure sharing of passwords. They often use encryption to protect your data, ensuring that only you can access your passwords. Popular examples of password managers include LastPass, 1Password, and Dashlane.
