Two-factor authentication for Microsoft products

Protect your organization from phishing attacks, account takeover, and data theft.

Two-factor authentication for Microsoft Remote Desktop (RDP), Outlook Web App (OWA), and Threat Management Gateway (TMG).

Strong Authentication for Your Microsoft Remote Access Points

Protecting remote access with two-factor authentication is the best way to protect your organization against phishing attacks, account takeover, and data theft. Duo Security enables you to easily deploy strong two-factor authentication on your Microsoft servers. Duo’s drop-in integrations for Outlook Web App (OWA), Remote Desktop (RDP), and Threat Management Gateway (TMG) make setting up and configuring Duo two-factor authentication fast and easy. Because Duo leverages your users’ existing devices — their mobile phones — as their authentication factor, deploying Duo two-factor authentication to your users is painless too.

Fast, Easy Integration and Deployment

It takes less than 15 minutes to configure Duo Security on your Microsoft servers. There’s no hardware to manage — just install our drop-in integrations and configure your server settings to take advantage of Duo’s authentication service. Duo has drop-in integrations ready to go for Outlook Web App (OWA), Remote Desktop (RDP), and Threat Management Gateway (TMG):

Duo also provides a well-documented Web SDK and Auth API so you can easily implement custom integrations with your in-house apps.

Clear, Simple User Experience

Duo’s self-enrollment and login prompts are displayed inline on your login pages either after the user completes primary authentication or as part of the same process. This provides a consistent and familiar experience for your users, which reduces your training time and support costs.

Duo Security supports diverse user types by allowing users to authenticate with whatever method is best for them. Some users will prefer the Duo Mobile app while others would rather carry a hardware token.

How Duo Security's Two-Factor Authentication Works

Works for Every User Anywhere

The Duo Mobile smartphone application is free and available on all major smartphone platforms, and lets users easily generate passcodes without the cost and hassle of hardware tokens. iPhone, Android, BlackBerry, and Windows Phone 7 users can use Duo Push which “pushes” login or transaction details to their phone, allowing the user to authenticate (or deny) a login attempt with just one-tap.

Older devices like cellphones and landlines are also fully supported. Duo can send passcodes via text message, or place a phone call to which users press a button on their keypad to authenticate.

Duo Security Offers Multiple Methods for Two-Factor Authentication

Duo also sells and supports hardware tokens for users who prefer them. Hardware tokens can be ordered from the Billing section of the administrative interface.
