xkcdpass generates secure random passwords that are (relatively) easy to memorize.

It uses a dictionary provided specifically for passphrase generation by the EFF and has an option for checking strength of the generated passwords using the zxcvbn library.

import (
  "github.com/happeens/xkcdpass"
)

// Create a 4-word password with strength score 4
password := xkcdpass.GenerateDefault()
