Duo is migrating from their long-used iframe authentication window to what they have chosen to call the Universal Prompt. When and how we migrate is up to us but there is a deadline of March 30, 2024 when the iframe method will no longer be available. We are planning to take our first step in this migration this coming Wednesday, February 1. Only logins to Microsoft 365 resources will be affected on Feb 1. See the Information Technology webpage for more detail and information.
