Duo Two Factor Authentication Setup
How does Duo work with VPN?
Duo is a Two-Factor Authentication (2FA) solution that adds an extra layer of security when accessing your VPN. It works by requiring users to provide additional proof of their identity, usually in the form of a temporary code or push notification, alongside their usual username and password.
When using Duo with a VPN, the process typically follows these steps:
1. The user enters their username and password in the VPN client.
2. After successful primary authentication, the VPN client sends a request to the Duo Authentication Proxy.
3. The Duo Authentication Proxy communicates with the Duo Cloud Service to determine the user’s preferred method of 2FA.
4. The user receives a push notification on their enrolled device, a phone call, or an SMS with a one-time passcode, depending on their chosen method.
5. The user approves the push notification or enters the one-time passcode into the VPN client.
6. The Duo Cloud Service verifies the response, and if successful, the user is granted access to the VPN.
By integrating Duo with your VPN, you can significantly increase the overall security, as it makes it much more difficult for unauthorized users to gain access even if they have obtained a user’s password. This extra protection is crucial, especially for organizations dealing with sensitive data or working remotely.
Does Duo have a VPN?
Duo itself does not offer a Virtual Private Network (VPN) service. However, Duo provides a Two-Factor Authentication (2FA) solution that can be integrated with various VPN providers to add an extra layer of security to the VPN connections. By using Duo’s 2FA, users must verify their identity through a second factor such as a mobile device before gaining access to the VPN network.
