A dictionary brute force will crack your password in seconds.

With that said, decrypting her method will be a bit more difficult but still crackable.

Fine so throw in a random made up word too.

My point is I don't see any real value being added here to be honest - as harsh as that sounds given that its a 11 year old's entrepreneurial venture.

You do know her words are from the dictionary as well ?

I build long, strong, memorable passwords using strings of words from the dictionary that I select using dice

So her's will be easily cracked.

OK, how is 6 random words she chose more secure than 6 random words I would choose?

Not really no. A typical oxford dictionary contains 171,476 words. 717476 ^ 6 = 25 422 605 913 456 636 373 066 491 006 976 possible combinations of 6 words. The average english word length is 5.1 characters.

Assuming your wordlist is encoded in ASCII (7/8 bits) and you don't have any new line characters or spaces your wordlist will be 5.1*6*25422605913456636373066491006976*7/8/1024/1024/1024/1024 = 61 908 419 714 454 910 000 0 TB in size.

Breakdown:
5.1 chars per word

25422605913456636373066491006976 possible combinations of 6 words
