The purpose of a password manager in cybersecurity is to help users securely store and organize their passwords. These tools generate strong, unique passwords for different accounts, significantly reducing the risk of credential theft. Password managers encrypt this sensitive information, ensuring it is accessible only to the user. Furthermore, they can automatically fill in login credentials to streamline user experience while browsing. By promoting better password hygiene and reducing reliance on memorable but weak passwords, password managers play a critical role in protecting personal and professional information online.
