The WA IIS implemented a Single Sign-On (SSO) login process on August 23, 2025. All IIS users will need to follow the linking process outlined in the Single Sign-on (SSO) for WA IIS Users guide to log into the IIS.
The IIS is now integrated with Secure Access Washington. Users access the IIS through Secure Access Washington by adding the IIS as a service (SAW guide PDF).
