			=== Response To GACRC Administrative Queries ===
			Users are responsible for monitoring the email associated with their GACRC account and responding in a timely manner to administrative requests from GACRC. These requests may relate to account or project information, security, compliance, resource usage, system operations, or other matters necessary to administer GACRC services. Failure to respond within the timeframe specified in a request may result in the suspension, modification, or termination of access to GACRC accounts, systems, or resources.

	===Sapelo2 Best Practices ===		===Sapelo2 Best Practices for Computational Biology ===
	~~Blurb~~		This workshop is primarily intended for researchers who have gained ''some'' hands-on experience conducting their own research on Sapelo2 but need an introduction to best practices for correct and efficient use of the cluster. Topics include best practices for loading and using software modules, correct allocation and use of computational resources (memory, CPUs, GPUs, etc.) and file systems, and important considerations for specific software packages; the examples covered will focus on bioinformatics, but the principles covered are broadly applicable to users across research areas.

==Duo Phone Call and SMS Text Verification Retirement Sept.17, 2026==

To enhance security and reduce phishing attempts, Enterprise Information Technology Services (EITS) is updating Duo multi-factor authentication (MFA) methods for all Duo users at the University of Georgia. These changes are part of EITS’ ongoing efforts to better protect UGA accounts.

As part of these improvements, EITS will remove the two less secure verification methods, SMS text messages and phone calls, and introduce more secure authentication options to safeguard UGA accounts.

===What is Changing?===

Beginning September 17, 2026, SMS text messages and phone calls will no longer be available as verification methods in Duo for students, faculty and staff. These methods are being retired because they are less secure.

The same change will go into effect for Departmental MyID accounts on November 5, 2026. Beginning on that date, SMS text messages and phone calls will no longer be available as Duo verification methods for Departmental MyIDs.

SMS text messages and phone calls were removed as verification methods for UGA retirees and owners of IT administrative accounts this summer.

===New Secure Authentication Options===

Effective Summer 2026, users have access more secure options, including:

* Duo Mobile app (push notifications and passcodes)

* Platform authenticators (such as fingerprint or facial recognition on your device)

* Roaming authenticators (such as USB security keys)

* Duo Desktop authentication (Duo authentication for your computer)

* Duo Hard Tokens (physical keychain devices that provide a Duo code)

===Why This Change Is Happening===

This change will remove two less secure MFA options in Duo while introducing more secure methods for logging in to UGA systems. These updates align Duo MFA with current security best practices and support enhanced protection for UGA systems and data.

==Additional Information===

To update your Duo Verification method, visit the [https://archpass.uga.edu/ Duo Self-Service portal].

For assistance in updating your method, contact the [https://eitshelpdesk.uga.edu/ EITS Help Desk].

For more information about these updates, available authentication methods and step-by-step resources, [https://eits.uga.edu/about-us/major-initiatives/duo-verification-methods-improvements/duo-improvements-overview/ visit the EITS Major Initiatives page: Duo Verification Methods Improvements].
