[![npm](https://img.shields.io/npm/v/omgopass.svg?color=%2356C838)](https://www.npmjs.com/package/omgopass) [![Build Status](https://travis-ci.com/omgovich/omgopass.svg?branch=master)](https://travis-ci.com/omgovich/omgopass) ![Dependencies](https://img.shields.io/david/omgovich/omgopass)

A tiny memorable password generator

- **Fast**: [600 times](#benchmark) faster than `password-generator`

- **Small**: 322 bytes (minified and gzipped)

- **Secure**: Uses [cryptographically strong random API](https://nodejs.org/api/crypto.html) 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](#benchmark) against popular password generation libraries, and omgopass currently beats them all.

### [Generate password online](https://omgovich.github.io/omgopass/)



### Install

```

npm install omgopass --save

```

### Usage

```js

import generatePassword from "omgopass";

const password = generatePassword(); // "Tu6Log5Bam4"

```

By default **omgopass** returns a random memorable password with size in range 9 to 12 characters.

To change password length you should config `syllablesCount`, `minSyllableLength` and `maxSyllableLength` options.

#### Advanced Usage

```js

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.

```js

generatePassword({

  minSyllableLength: 4,

  maxSyllableLength: 6,

  hasNumbers: false,

  titlecased: false,

  separators: " "

}); // "goferu lipeba cyzex"

```

### Who uses omgopass

- [LogChimp](https://github.com/logchimp/logchimp) — self-hosted platform for products makers to get feedback from their users

- [Laravel VPN Admin](https://github.com/Laravel-VPN-Admin/api-core) — Admin panel for VPN servers management

- [Password Pusher](https://github.com/pglombardo/PasswordPusher) - application to securely communicate passwords over the web

### Supporting IE11 and obsolete platforms

This library uses features like [destructuring assignment](https://kangax.github.io/compat-table/es6/#test-destructuring,_assignment) and [`const/let` declarations](https://kangax.github.io/compat-table/es6/#test-const) 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`
