What is passphrase vaulting?

Passphrase (or password) vaulting is the practice of storing many different passwords and passphrases behind a single, strong passphrase. If you have several different passwords and passphrases (e.g., for online banking, email accounts, and other secure applications), you may have difficulty remembering them when needed. Rather than compromising security by repeating passphrases among applications or by physically writing the phrases down, you can employ passphrase vaulting to store all the phrases behind one secure, but easily remembered, passphrase.
