  • -l, --length <usize>: Set the length of the password (default: 8)
  • -a, --allowed <STRING>: Set the allowed character sets (comma-separated) [default: digit,lowerletter,upperletter,symbol1,symbol2]
  • -e, --exclude <STRING>: Exclude specific characters (comma-separated)

  • -n, --num <usize>: Set the number of passwords to generate (default: 1)
  • -s, --stats: Display statistics about the generated passwords
  • -r, --avoid-repeating: Avoid repeating characters in the password
  • -d, --diceware: Generate a password using the Diceware method
  • -w, --words <usize>: Set the number of words to generate (default: 6)

Examples

Generate a password with the default length (8 characters):

npwg -l 12

Generate a password that includes only digits and lowercase letters:

npwg -a digit,lowerletter

Generate a password that excludes specific characters:

npwg -e 0,O,l

Generate a password that forces the inclusion of specific characters:

npwg -i 1,2,3

Generate 5 passwords at once:

npwg -n 5

Generate a password with a custom length and character sets:

npwg -l 16 -a digit,lowerletter,upperletter,symbol1,symbol2

Display statistics about the generated password:

npwg -s

Generate a password using the Diceware method. If no diceware wordlist is in ~/.npwg, it will be automatically downloaded from the EFF website:

npwg -d

Generate a password using the Diceware method with a custom number of words. The default number of words is 6. The wordlist will be downloaded if it is not found in ~/.npwg:

npwg -d -w 8
