A single user identification entrance (auth). Potpie utilizes one time passwords (OTP) which are compatible with Google Authenticator on both Android and iPhone. It's time to ditch that HTTP Basic authentication for an even easier method.

Installation

Add this line to your application's Gemfile:

gem 'potpie'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install potpie

Usage

Configuration

Create a new file titled potpie.rb within config/initializers/. Set both base32_secret and user_email to your own unique values. We HIGHLY recommend you store these values in Environment variables.

Potpie.configure do |config|
  config.base32_secret = ENV["POTPIE_CONFIG_BASE32_SECRET"]
  config.user_email = ENV["POTPIE_CONFIG_USER_EMAIL"]
end

Upon installation of Potpie, feel free to utilize our builtin Base32 string generator within the rails console to provide a unique Base32 string. However, creating your own is okay too (16 chars in length).

Potpie.random_base32
 => "wil3usmyllhhrgvm"

Generate QR Code or Provisioned URI

Potpie.generate.provisioned_uri
=> "otpauth://totp/test@email.com?secret=wil3usmyllhhrgvm"

# TODO
# Potpie.generate.qr_code

Utility Methods

Return the current time-based one time password value

Potpie.now
=> "710571"
