What is generate-password?

The generate-password npm package is a utility for generating random passwords with various customizable options. It allows developers to create passwords with specific lengths, character sets, and patterns, making it useful for applications that require secure password generation.

What are generate-password's main functionalities?

Generate a simple password

This feature allows you to generate a simple password with a specified length and the inclusion of numbers. The code sample generates a 10-character password that includes numbers.

const generatePassword = require('generate-password');
const password = generatePassword.generate({
  length: 10,
  numbers: true
});
console.log(password);

Generate multiple passwords

This feature allows you to generate multiple passwords at once. The code sample generates an array of 5 passwords, each 10 characters long and without uppercase letters.

const generatePassword = require('generate-password');
const passwords = generatePassword.generateMultiple(5, {
  length: 10,
  uppercase: false
});
console.log(passwords);

Custom character set

This feature allows you to generate a password with a custom set of characters. The code sample generates a 12-character password that includes numbers, symbols, uppercase, and lowercase letters, while excluding similar characters.

const generatePassword = require('generate-password');
const password = generatePassword.generate({
  length: 12,
  numbers: true,
  symbols: true,
  uppercase: true,
  lowercase: true,
  excludeSimilarCharacters: true
});
console.log(password);
