Picking a Passphrase

What is a "passphrase"?

A passphrase is a type of password that consists of multiple words that may form a sentence or other series of words in a certain context that is easy to remember for the user. 

Are they as secure as traditional passwords?

Yes.  As they tend to be longer than a password, that additional number of characters makes them more secure.  But the important thing is length, not complexity.  A passphrase of 16 or more characters (e.g., So one like this.) takes MUCH longer to crack than an 8 character complex one (e.g., N0t2-be!).

What should I avoid when making a passphrase?

As with any password, you should avoid selecting a passphrase that is easily guessed by another.  For example, if you have a favorite quote that you use on social media or frequently in conversation or just like, that quote would not be a good choice as a passphrase for your accounts.  You should also avoid common phrases like those in nursery rhymes and popular song lyrics.

Do passphrases have any drawbacks?

Because a passphrase's security typically comes from its length, passphrases can be cumbersome for anyone who needs to enter their password frequently throughout the day.  For example, an average typist logging into a device or service twenty times a day using a forty character passphrase will lose between ten to fifteen minutes a day in password entry.  Always consider how using a long passphrase will impact your day before selecting one, and compensate for any reduction in length with an increase in complexity (such as exchanging letter characters with special ones).
