Why Word-Based Passwords?
As famously illustrated by XKCD #936, a password like correct-horse-battery-staple is both easier to remember AND more secure than something like Tr0ub4dor&3.
Tr0ub4dor&3
~28 bits entropy, hard to remember
correct-horse-battery-staple
~44 bits entropy, easy to remember
Security Comparison

Tips for Memorable Passwords
- Create a mental image or story connecting the words
- Use more words for higher assurance; 6 words from this vocabulary provide about 58 bits of ideal entropy
- Adding a number or symbol increases security with minimal memory burden
- Each independently selected word multiplies the search space by 768
- Still use unique passwords for each account - use a password manager!
