Question 1

What is a passphrase?

Accepted Answer

A passphrase is a sequence of random words (e.g., "correct-horse-battery-staple"). Passphrases are easier to remember than random character passwords while providing comparable or better security.

Question 2

How many words should a passphrase have?

Accepted Answer

A 4-word passphrase from a 7776-word list provides ~51 bits of entropy. For high security, use 5-6 words (~65-78 bits).

Question 3

Is a passphrase more secure than a password?

Accepted Answer

A well-chosen passphrase can be both more secure and more memorable than a traditional password. The key is using sufficient word count and random selection.
