Why shuffle? Does it do something rand doesn't already do?

At any rate, would probably want to use https://ruby-doc.org/stdlib-2.5.1/libdoc/securerandom/rdoc/S... for password generation.

Also, I think you might just want an alphabet and use sample: https://ruby-doc.org/core-2.5.1/Array.html#method-i-sample

# unsure if you need a:

require 'securerandom'

(33..126).sample(14, random: SecureRandom).map(&:chr).join

You're right, probably doesn't need shuffle :)

And 3x more possibilities because it allows the same character more than once. But I think the last shuffle is not necessary

Thanks! Learned something new today (even though I’m mostly on Python now)
