- sliverstorm 15y agoPut another way, Oxford lists over 250000 words in English. There are 26 letters. So we have: 250000^4 = 4 x 10^21 combinations vs 26^(~10 characters) = ~10^14 combinations Even counting for capitolization and numbers and symbols, you get something like: 72^(~10) = 4 x 10^18

- sliverstorm 15y agoYeah, well, even if you use 1/8 of the Oxford dictionary you're still around parity with a 10-symbol password using lower case, capitols, symbols and numbers. At which point we fall back to Randall's observation- one is a whole hell of a lot easier to remember than the other.
