Dictionary Based Password Generator - Cross-Platform Chrome App
The built-in dictionary has 4,950,765,090 possible combinations, and it'll give you six new choices each time you open the app, or hit the refresh button. Then simply click the password you like the most, and it's automatically copied into your clipboard. From there you can paste it wherever you like.
This app generates passwords with enough length and combinations to make anyone guessing your passwords unlikely, even if they had the same dictionary of words. Why not just use the generator that came built into your password manager? Password managers generate passwords that 'look' difficult as they use random letters, numbers, and symbols - they are difficult for humans since they are very hard to type and remember. To a computer, they're not much different from words - so arguably - there isn't much to gain from the trade-off.
