A Password Vault is a secure digital storage solution designed to keep your passwords and sensitive information safe. It allows users to store, manage, and retrieve their passwords easily, often using encryption to protect the data from unauthorized access. Many password vaults also offer features like password generation and autofill, making it easier to create strong passwords and log into accounts. Using a password vault can enhance your online security by encouraging the use of unique passwords for different accounts, reducing the risk of breaches. Popular examples of password vaults include LastPass, 1Password, and Dashlane, which provide user-friendly interfaces and additional security features.
