This is a very simple class for creating random pronounceable passwords. By default it also uses special characters and numbers, but this can be disabled. One can also customize the letter combinations that are allowed, as well as character replacements.

Note: This class is not based on, nor does it have anything to do with, other similar projects with the same name.

• PHP 7.4 or newer
• mbstring extension

Install with composer:

composer require ensnared/pwgen

To create a password with default settings, simply use Password::create();.

By default, the passwords generated will be between 8 and 12 characters long, and will include at least 2 special characters and 2 digits.

The behaviour can be configured with the methods below. All these methods also have an equivalent get-method.

• Password::setConsonants()
  • Set list of consonants used in password creation.
  • Default is all consonants in the english alphabet.
• Password::setDigits()
  • Set number of digits to add to end of password.
  • Default is 2.
• Password::setDoubleConsonantsAfterVowel()
  • Set the list of double consonants that will only be used after a vowel in a password.
• Password::setDoubleConsonantsAnywhere()
  • Set the list of double consonants that can be used anywhere in a password.
• Password::setDoubleConsonantsFirst()
  • Set the list of double consonants that will only be used in the beginning of a password.
• Password::setDoubleVowelsAfterConsonant()
  • Set the list of double vowels that will only be used after a consonant in a password.
• Password::setDoubleVowelsAnywhere()
  • Set the list of double vowels that can be used anywhere in a password.
• Password::setDoubleVowelsFirst()
  • Set the list of double vowels that will only be used in the beginning of a password.
• Password::setMaxLength()
  • Set the maximum length of generated passwords.
