1.13 PASSWORD MANAGER
A password manager is a specialised software tool designed to help users securely store, manage, and retrieve their
login credentials for numerous websites, applications, and services. Instead of memorising different passwords for
each account, users only need to remember one master password, which grants access to the entire password vault.
This master password is a single, strong passphrase that serves as the encryption key for securing stored credentials
and the decryption key for unlocking them when needed.
By using a password manager, users can create complex, unique passwords for each account, enhancing security
without the risk of forgetting them. The password manager ensures that each password is encrypted, protecting it
from unauthorised access.
