East Tennessee State University is phasing out traditional Multi-factor Authentication (MFA) methods, specifically SMS text messages and automated phone calls, and is launching stronger security options to protect accounts from phishing attacks.

This global security update driven by Microsoft will begin taking effect on Feb. 1, 2027. Any student, faculty or staff member still relying solely on texts or phone calls after that date will be unable to log in until they register a new method. This change is primarily to protect ETSU from modern cyber threats like SIM-swapping, real-time phishing and code interception.

The primary recommended replacements are the Microsoft Authenticator app and Passkeys; hardware security keys are also supported for those who require non-smartphone alternatives

“Our goal is to get everyone moved over well before the February 1 deadline, so nobody gets locked out when spring classes are in full swing,” said Adam Greever, ETSU’s Help Desk manager. “It takes less than five minutes to set up the Microsoft Authenticator app or a Passkey, and once you do, signing in is both safer and faster than waiting on a text message.”

To make this transition as easy as possible, the ITS team will offer walk-up support at the Culp Student Center (1st Floor Main Street Booth 5) on weekdays from November 12–20, between 10 a.m. and 2 p.m. Students can also contact the ITS Help Desk by email at itshelp@etsu.edu or by phone at 423-439-4648. Additional information is available on the Multi-factor Authentication webpage.
