Strong Authentication for SSH & Unix
Protecting local (SSH) and remote Unix logins with strong two-factor authentication is the easiest and most cost-effective way to secure your infrastructure against today’s cyberthreats. Duo Security makes it easy to deploy two-factor authentication across your organization because it takes advantage of users’ existing devices — their mobile phones.
Duo’s Unix integration is open source and can be easily installed on all major Unix distributions — no hardware required. Users are given a web link to enroll and register their own phones, making deployment fast and painless.Learn how to protect SSH logins with Duo Unix »
Works for Everyone
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 users can use Duo Push which “pushes” login or transaction details to the phone, allowing for immediate, one-tap approval.

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