Using a phrase or sentence, not one word, as your password
A passphrase is similar to a password. It is used to verify access to a computer system, program or service. Passphrases are most effective when they are:
- Used with multi-factor authentication
- Unique – not a famous phrase or lyric, and not re-used
- Longer – phrases are generally longer than words
- Complex – naturally occurring in a sentence with uppercase, symbols and punctuation
- Easy to remember – saves you being locked out.
Passphrases create greater security and more convenience
- Harder to crack against common password attacks
- Easier to remember than random characters
- Meets password requirements easily – upper and lower-case lettering, symbols and punctuation
Brute force attacks and dictionary attacks both generate millions of password/passphrase attempts per second.
For all fixed and mobile devices
Passphrases will significantly increase security across all of your business’ devices. See below for a comparison of password vs passphrase security.
|Password/ passphrase||Time to crack||Easy to remember||Comments|
|Brute force attack||Dictionary attack|
|password123||Instantly. Less than AU$0.01||Instantly. Less than AU$0.01||Very easy (too easy)||One of the most commonly-used passwords on the planet.|
|Spaghetti95!||48 hours AU$587.50||Less than half an hour AU$6.10||Easy||Some complexity in the most common areas, and very short length. Easy to remember but easy to crack|
|5paghetti!95||24 hours AU$293.70||Less than 1 hour AU$12.20||Somewhat easy||Not much more complexity than above with character substitution, and still short length. Easy to remember but easy to crack.|
|A&d8J+1!||2.5 hours AU$30.60||2.5 hours AU$30.60||Very difficult||Mildly complex, but shorter than the above passwords. Hard to remember, easy to crack (against BFA).|
|I don’t like pineapple on my pizza!||More than 1 year. More than AU$107,222.40||More than 40 days. More than AU$11,750.40||Easy||Excellent character length (35 characters). Complexity is naturally high given the apostrophe, exclamation mark and use of spaces. Very easy to remember and very difficult to crack.|
