jQuery.vibrate.js: Trigger mobile device vibrations

jQuery.vibrate.js lets you trigger vibrations on mobile devices in the pattern and duration you choose. It’s very simple to use, with a number of options for when to trigger vibrations and how long those vibrations should last (there’s even a handy chart so you can check out the durations for yourself).

However, this doesn't mean that your device can vibrate. Just that it's recent enough. There are a few requirements you need to meet.

1. You need the hardware for it.
2. The page needs to be visible.
3. Browser-specific implementation prevents the vibration.

Passwordless: Authentication middleware for Express & Node.js

Passwordless is a token-based password authentication middleware for Express and Node.js. It’s faster to deploy, with just a single form and text field, with no need for separate registration, login, and lost password pages.

node.js/express module to authenticate users without password 

Passwordless

Passwordless is a modern node.js module for express that allows authentication and authorization without passwords by simply sending one-time password (OTPW) tokens via email or other means. It utilizes a very similar mechanism as the reset password feature of classic websites. The module was inspired by Justin Balthrop's article "Passwords are Obsolete"

Check out a demo and further documentation on https://passwordless.net or have a look at an example.

Token-based authentication is...

• Faster to implement compared to typical user auth systems (you only need one form)
• Better for your users as they get started with your app quickly and don't have to remember passwords
• More secure for your users avoiding the risks of reused passwords
