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

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/Securerandom.html 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 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
