Fixed an issue where Duo requires two factor authentication for users logging into the incorrect site in WPMU, even if that user doesn't have a role that requires admin on any site in the WPMU network.
duo_wordpress - Duo two-factor authentication for WordPress logins
Duo provides simple two-factor authentication as a service via:
- Phone callback
- SMS-delivered one-time passcodes
- Duo mobile app to generate one-time passcodes
- Duo mobile app for smartphone push authentication

This WordPress plugin allows you to quickly add Duo's interactive, self-service, two-factor authentication to any WordPress login.
