A Password Manager is a software application designed to store and manage online credentials securely. It generates, retrieves, and keeps track of complex, unique passwords for multiple accounts without requiring the user to remember each one. Instead, users only need to remember one master password to access their password vault. Modern password managers often include features such as secure password generation, auto-fill capabilities for web forms, cross-device synchronization, and security alerts for compromised passwords. Many also offer secure sharing of passwords among team members or family. By encouraging the use of strong, unique passwords for each account and eliminating the need to memorize them, password managers significantly enhance an individual's or organization's security posture while improving user convenience.
