Duo FAQ | Single Sign-On (SSO) & Microsoft RDP 2FA Explained

Duo IAM FAQ – Single Sign-On & RDP 2FA

1. Does Duo support Microsoft Remote Desktop (RDP)?
Yes. Duo integrates directly with Microsoft Remote Desktop (RDP) to add two-factor authentication (2FA). This means that even if an attacker steals a password, they cannot log in without the second authentication factor, protecting your systems from ransomware and brute-force attacks.

2. How does Duo Single Sign-On (SSO) work?
Duo Single Sign-On (SSO) allows employees to use one secure login to access all business applications—whether on-premise or in the cloud. Duo verifies user identity, device health, and location before granting access, helping you reduce password fatigue and improve security at the same time.

3. Can Duo integrate with Microsoft 365 and other cloud apps?
Yes. Duo SSO supports popular platforms such as Microsoft 365, Google Workspace, Salesforce, Dropbox, and more. This makes it easier for small businesses to secure both remote desktops and cloud-based productivity tools with one solution.

4. What two-factor authentication (2FA) methods does Duo support?
Duo offers multiple 2FA methods, including:

Duo Push (mobile app approval)
SMS passcodes
Phone call verification
Hardware tokens

This flexibility ensures that all employees, regardless of device preference, can use Duo securely.

5. Does Duo help with compliance (HIPAA, PCI, GDPR)?
Yes. Duo helps businesses meet regulatory requirements by enforcing strong authentication, detailed access logs, and security policies. For healthcare, finance, and legal industries, this is critical for compliance with HIPAA, PCI DSS, and GDPR.

6. Is Duo easy for employees to use?
Absolutely. Duo is designed for simplicity. Employees can approve logins with a single tap on their phone, making it both secure and user-friendly. The onboarding process is straightforward, and our IT team provides full support and training.

7. How quickly can Duo be deployed?
