Random words are easier to remember and type than random characters, and as strong when there are enough of them.
The EFF's list.
The Electronic Frontier Foundation made a list of 7,776 words, one for each roll of five dice, chosen to be easy to spell and type. The page picks words from it with the browser's own randomness.
How many words.
Each word adds log₂ 7,776 ≈ 12.9 bits, so six words give about 77 bits and seven about 90.
Chosen, not picked.
Words you pick yourself are far easier to guess; the strength holds only when the computer chooses them.
