The OTP, One-Time Password, module provides an additional layer of security to the login process by requiring users to enter a randomly generated one-time password in addition to their regular Drupal password.
The one-time password is generated from within your Drupal system and can be sent via email or SMS. No physical token generator/dongle is required.
Not all users require OTP access on a Drupal system. So, OTP provides the option to enable OTP authentication based on user roles.
Implements authentication using Authy. Requires the drupSec module, also found in my sandbox.
The main googleajaxsearch module allows you to add inline searches over a number of Google services (Web Search, Local Search, Video Search, Blog Search, and News Search).
