A password manager is a computer program that allows users to store, generate, and manage their passwords for local applications and online services. Think of it like a safe for your passwords. When you need something inside the safe, you unlock it. Password managers work the same for your online credentials.
You create a single, super-strong password, which acts like a key. Install the password manager app on your phone, computer, browser and other devices. Your passwords are securely stored inside it. Anytime you need to log in to an account, unlock your password manager and retrieve your login info.
