Can you give some specs on your Diceware solution:
1. Number of dictionary entries (e.g. Diceware is 7776. How long is yours?)
2. word size range (shortest to longest) Looks like 3-8, correct?
3. What's the entropy value for each word in the password string.
Can you add "none" to the delimiter list? Some of us like to just type word strings quickly. A little more readability difficulty is not an issue in most cases
Can you add ";" (semicolon) to the delimiter list?
This is the fastest and easiest delimiter to type since it's right under the right hand 4th finger.
Can you add initial caps such as: BreakSettlerButtonDestination
This might be lowest priority; a user survey might help determine whether to include this.
I know there's a risk of making the list excessive, but I think, at least, the first 2 would be popular additions.
