User Access & Authentication

This module aims to integrate HybridAuth with Drupal so that you can allow your end-users to login and register using Twitter, Facebook, Google, Yahoo, Windows Live, MySpace, Foursquare, Gowalla, PayPal, LinkedIn, OpenID, Tumblr, Friendster, Vimeo, AOL, Flickr, and more.

HybridAuth is an open source web-based authentication and authorization solution that combines the strengths of several major social networks and Identity Providers services into one simple PHP Library.

Main Features:

xAuth aims to provide a relatively simple, secure and flexible cross site authentication mechanism. This could be used for one-directional Single Sign On (SSO) between a non-Drupal system and your Drupal instance.

Allow user to login/register by certificate either automaticly (transparent) or by login page. (Only Drupal 7).

This module extends Profile 2 by allowing administrators to create privacy levels as predefined groups or sets of profile fields on a per role basis. Users can then select from among the privacy levels to apply access control to their profile.

Requirements:

Profile 2

Project to provide an all in one login popup for registration, login, password retrieval.

Allows users of a remote Services-enabled Drupal site to sign on with their credentials into this site.

Overview

This module accelerates the time to implement Janrain Registration into your Drupal web sites, helping you to improve your registration conversion rates by allowing your customers to register and sign-in through their Social Network of choice.

Federal employees and contractors are issued Personal Identify Verification (PIV) compliant cards (often known as CAC cards) for authentication within government buildings, sites, and resources such as machines and other applications. This module supports the current PIV architecture in a variety of government sites, and allows users to login to a Drupal web application with only a client certificate in the browser.

With this module you can lock fields in a webform so that those fields cannot be deleted or modified except by administrators with appropriate permissions. It was written to work in tandem with the Webform Default Fields module but is not dependent upon it. The idea is that if you create default fields for a webform, you may want to ensure consistency by preventing webform creators from modifying some or all of the default fields.
