Overview#Password Vault (or Password Manager) is any software application or hardware that helps a user store and organize passwords.
Password Vault hopefully store passwords using encryption, requiring the user to create a master password: a single, ideally very strong password which grants the user access to their entire password database.
Password Vault may store passwords on the user's computer (called offline password managers), whereas others store data in the provider's Cloud Service (often called online password managers). However offline password managers also offer data storage in the user's own cloud accounts rather than the provider's cloud.
Many LDAP server implementations are is also a Password Vault.
