Once the master password is entered, the password manager can automatically fill in login credentials for websites and applications without the user having to remember the passwords themselves. This vault is encrypted with a master password, which is used to unlock the vault and access the stored passwords. Password managers typically work by creating a “vault” or “database” where users can store their passwords. It is designed to make it easier for users to create, store, and retrieve complex passwords for multiple accounts without remembering them all. A password manager is a tool or software application that helps users manage and store their passwords securely.
