Google Authenticator login

This module will allow you to add Time-based One-time Password Algorithm (also called "Two Step Authentication" or "Multi-Factor Authentication") support to user logins. It works with Google's Authenticator app system and support most (if not all) OATH based HOTP/TOTP systems.

Remark

If you want to protect uid 1, you have to enable the option 'Protect my account with two-factor-authentication' on user/1/edit!

Dependencies

• Google authenticator app for Android, IPhone or Blackberry
• Or a desktop client (should work on all operating systems)
• Or a windows, palm os, java phone client

Recommended Modules

This module now supports both QR Codes and Mobile Codes, although we recommend using Mobile Codes, because it has more flexibility (there is a default preset for Mobile Codes which can be altered to your need: different providers and adjustable options per provider)
