Diceware

First, feel free to check out the live demo, running at https://www.dmuth.org/diceware/

Weak passwords are a big flaw in computer security due to a lack of "entropy" or randomness. For example, how many times have you used the name of a pet or relative or street in a password, or perhaps the number "1". Not very random, is it? :-) Worse still, if passwords are reused between services, that increases your security risk.

Fact is, humans are terrible at remembering random combiations of letters and numbers, but we are great at remembering phrases of words. That's where Diceware comes in.

Diceware is based on the proposal at http://world.std.com/~reinhold/diceware.html wherein virtual dice are roled 5 times, and the 5 digit number used against a lookup table of words. 4 dice rolls gives you 4 random words which are easy for a human being to remember, yet have a high amount of entropy which makes them hard to crack.

Can I run this on my own computer without using your website?

Yes. Feel free to clone this repo with git clone https://github.com/dmuth/diceware.git and run it from a local directory on your computer.

Will this work on an iPhone?

Yep! It should work on any mobile phone or tablet that supports Javascript, but I have only tested it on an iPhone 5S at this time.
