PassPhrase (Longer password)

1 - About

A passphrase is something you know and is like a password except:

  • it is longer (not always true)
  • it's not coupled to a login

In the early days passwords on Unix system were limited to 8 characters, so the term passphrase for longer passwords.

Longer is the password harder it is to guess.

Nowadays Unix systems use MD5 hashes which have no limitation in length of the input (ie password).
