The single sign-on (SSO) authentication method allows users to securely authenticate with multiple applications and websites by using just one set of credentials, usually an institute-issued one. Yesterday at the ESRI User Conference, I was told by ESRI Reps that ESRI would enforce SSO beginning January 1st, 2025 and all other licensing options would be gone. This news shocked me with such a short time turnaround. I would like to express my concerns here.
Of course, SSO is convenient and safe. We don't need to remember two separate sets of credentials for My ESRI and ArcGIS Online. But the downside is also obvious: you cannot assume you always have a reliable internet connection. Our campus is located in a tornado-threaten area. Last year alone, our campus experienced severe campus-wide (sometimes city-wide) internet outages for various of reasons such as weather, accidents, equipment failure, etc. Most of those internet outages lasted several hours or even longer. More importantly, not all our students have reliable internet connection at homes. Previously, single-use license works well for our GIS major students who need to access to ArcGIS Pro frequently from their own computer. Many of our students have multiple jobs besides being a full-time students because of financial burden. They might not have reliable internet at home. I remember some of my former students drove to campus and stayed in the parking lot so that they can have reliable WIFI if they were taking an online quiz or exam during the pandemic. Aftere pandemic, they no longer need to be stucked in the parking lot, but it is prevalent among students to leverage the free internet connectivity on campus. It is probably understandable to take a quiz or exam, but it might be too much due to the SSO requirement of ArcGIS Pro. My students need to work on ArcGIS Pro several hours at least for one single assignment.
I wish single-use license option can last longer, much longer so that we can have some alternatives for students who need it or in the filed we don't have internet connection.
