Passwordless-RedisStore

This module provides token storage for Passwordless, a node.js module for express that allows website authentication without password using verification through email or other means. Visit the project's website for more details.

Tokens are stored in a Redis database and are hashed and salted using bcryptjs.

bcryptjs has the disadvantage of being slower than the native implementation of bcrypt but is easier to install on Windows machines. If you're looking for an implementation using the native version of bcrypt please use passwordless-redisstore.

Usage

First, install the module:

$ npm install passwordless-redisstore-bcryptjs --save

Afterwards, follow the guide for Passwordless. A typical implementation may look like this:

var passwordless = require('passwordless');
var RedisStore = require('passwordless-redisstore-bcryptjs');

passwordless.init(new RedisStore(6379, '127.0.0.1'));

passwordless.addDelivery(
    function(tokenToSend, uidToSend, recipient, callback) {
        // Send out a token
    });
    
app.use(passwordless.sessionSupport());
app.use(passwordless.acceptToken());

Initialization

new RedisStore([port], [host], [options]);

• [port]: (Number) Optional. Port of your Redis server. Defaults to: 6379
• [host]: (String) Optional. Your Redis server. Defaults to: '127.0.0.1'
• [options]: (Object) Optional. This can include options of the node.js Redis client as described in the docs and the ones described below combined in one object as shown in the example

Example:

passwordless.init(new RedisStore(6379, '127.0.0.1', {
	// option of the node.js redis client
    auth_pass: 'password',
    // options of RedisStore
    redisstore: {
        database: 15,
        tokenkey: 'token:'
    }
}));

Options

• [redisstore.database]: (Number) Optional. Database to be used. Defaults to: 0
• [redisstore.tokenkey]: (String) Optional. Keys to be used. UIDs will be appended. Defaults to: 'pwdless:UID'

Hash and salt

As the tokens are equivalent to passwords (even though only for a limited time) they have to be protected in the same way. passwordless-redisstore uses bcrypt with automatically created random salts. To generate the salt 10 rounds are used.

Tests

$ npm test
