Removal of passcodes from Duo Risk-Based Factor Selection methods

  • Duo’s Risk-Based Factor Selection (RBFS) policy will no longer allow passcodes via SMS, Duo Mobile, and hardware token as RBFS step-up authentication methods.
  • The change will affect end-users logging into applications protected by RBFS policy. When RBFS detects a risk pattern and requires a step-up authentication from an end-user, the end-user will not be able to use passcode methods to complete the step-up authentication until the end-user completes MFA with a more secure method. 
  • Going forward, RBFS step-up authentication will offer the following methods:

WebAuthn FIDO2 security keys with biometric or PIN verification

Platform authenticators like Touch ID or Windows Hello 

Verified Duo Push

Bypass codes provided by a Duo administrator

  • This change will not apply to the Auth API.

 

Why has Duo removed passcodes as a RBFS step-up authentication method? 

This change will improve Duo protection from passcode phishing. 

As our customers’ trusted advisor in secure access, we are committed to developing Risk-Based Authentication policies that provide the strongest protection possible in response to high-risk authentication patterns. 

We have learned from our research that passcodes no longer give our customers the protection they need from high-risk threats. By collaborating with customers on the research of threat actor capabilities, Duo has verified that attackers are increasingly targeting passcodes to gain access to protected applications. 



Operating systems policy updated

  • iOS 17 and macOS 14 Sonoma are now available in operating systems policy.
  • Duo operating systems policy will now recognize iOS 17 as the latest, and iOS 16 as up-to-date.
  • On September 21, 2023, Apple released critical security updates to iOS 17 and iOS 16, but not iOS 15. Therefore, Duo will now recognize iOS 15 as end-of-life.
