The main difference between passwords and passphrases is their length. Passwords are rarely longer than 15 characters, but passphrases commonly contain 20 or more characters. </p> <a name="wp9000493"> </a><p class="pBody"> Complexity and dictionary checks are less important for passphrases as passphrases rely primarily on length for security. You may therefore want to relax some password policy requirements for passphrases.
