omgopass

A tiny memorable password generator

• Fast: 600 times faster than password-generator
• Small: 322 bytes (minified and gzipped)
• Secure: Uses cryptographically strong random API instead of Math.random
• No dependencies
• Supports Node.js and browsers

Why you should consider using omgopass in your project? The library's goal is to provide the fastest and the smallest (in terms of the bundle size) password generation solution. We have performed a bunch of benchmarks against popular password generation libraries, and omgopass currently beats them all.

Generate password online

Install

npm install omgopass --save

Usage

import generatePassword from "omgopass";
const password = generatePassword(); // "Tu6Log5Bam4"

Advanced Usage

generatePassword({ hasNumbers: false }); // "MunBedKod"

generatePassword({ syllablesCount: 5 }); // "Rot2Ba5Vim1My8Red4"

generatePassword({ titlecased: false }); // "si5co3ve8"

generatePassword({
  syllablesCount: 4,
  minSyllableLength: 3,
  maxSyllableLength: 4,
  hasNumbers: false,
  titlecased: true,
  separators: "-_",
  vowels: "аеиоуэюя",
  consonants: "бвгджзклмнпрстчш"
}); // "Зер_Коти-Лов_Меч"

Recipe: Generate random passphrase

Looking for long passwords that are easy to remember but hard to guess? Try to generate random passphrase instead.

generatePassword({
  minSyllableLength: 4,
  maxSyllableLength: 6,
  hasNumbers: false,
  titlecased: false,
  separators: " "
}); // "goferu lipeba cyzex"

Available options

Name	Description	Default
syllablesCount	Integer, count of syllables	3

Supporting IE11 and obsolete platforms

This library uses features like destructuring assignment and const/let declarations and doesn't ship with ES5 transpiled sources. If you aim to support browsers like IE11 and below → make sure you run Babel over your node_modules
